Description
本專利申請案主張於2020年7月28日提出申請的標題為「INTEGRATED CIRCUIT (IC) PACKAGE WITH STACKED DIE WIRE BOND CONNECTIONS, AND RELATED METHODS(具有堆疊晶粒引線鍵合連接的積體電路(IC)封裝及相關方法)」的美國專利臨時申請案第63/057,552號的優先權,該臨時專利申請案的全部內容經由引用之方式併入於本文。
本案的技術大體而言係關於具有與其相關聯的多個晶粒的積體電路(IC)封裝以及用於此類封裝的引線鍵合連接。
在現代社會中,計算設備,尤其是行動通訊設備比比皆是。此類計算設備依賴於積體電路(ICs),該IC可被組合到單個封裝中以提供增加的功能性。此類封裝可包括堆疊在彼此頂部且耦合至基板(諸如印刷電路板(PCB))的IC。在許多情形中,第一IC經由焊料凸塊等耦合到基板,而堆疊IC可經由引線鍵合連接耦合到基板。對以增加的操作速度來應對增加的功能性的需求在繼續,從而導致需要以最小的潛時來提供封裝。此類需求在遵從日益嚴格的蜂巢通訊標準的行動計算設備中尤其尖銳。
本詳細描述中揭示的各態樣包括具有堆疊晶粒引線鍵合連接的積體電路(IC)封裝和相關方法。在示例性態樣中,IC封裝具有兩個堆疊IC晶粒,其中第一晶粒直接耦合到金屬化結構,並且堆疊在第一晶粒頂部的第二晶粒經由引線鍵合連接來連接到金屬化結構。IC晶粒經由金屬化結構的內部金屬層彼此耦合。通孔被用於耦合到內部金屬層。藉由穿過基板的內部金屬層來佈線,可以縮短總連接長度,這進而減少與連接相關聯的電阻和電感。降低的電阻和電感減少與電阻和寄生電感相關聯的損耗。
就此而言,在一態樣中,揭示一種積體電路(IC)封裝。該IC封裝包括金屬化結構,該金屬化結構包括金屬層。該IC封裝亦包括:經由金屬化結構內的引線鍵合連接和通孔耦合到金屬化結構內的金屬層的IC晶粒。
在另一態樣中,揭示一種IC封裝。該IC封裝包括金屬化結構。該金屬化結構包括第一金屬層和與第一金屬層分離的第二金屬層。該IC封裝亦包括毗鄰於該金屬化結構並且耦合到第二金屬層的第一IC晶粒。該IC封裝亦包括毗鄰於第一IC晶粒的第二IC晶粒。第二IC晶粒經由通孔耦合到金屬化結構的第二金屬層,其中第一IC晶粒經由第二金屬層耦合到第二IC晶粒。
在另一態樣中,揭示一種製造IC封裝的方法。該方法包括:形成包括第一金屬層和第二金屬層的金屬化結構。該方法亦包括:經由通孔來將第一金屬層中的觸點焊盤連接到第二金屬層。該方法亦包括:經由引線鍵合連接來將IC晶粒連接到觸點焊盤。
現在參照附圖,描述本案的若干示例性態樣。措辭「示例性」在本文中用於意謂「用作示例、實例,或說明」。本文中描述為「示例性」的任何態樣不必被解釋為優於或勝過其他態樣。
本詳細描述中揭示的各態樣包括具有堆疊晶粒引線鍵合連接的積體電路(IC)封裝和相關方法。在示例性態樣中,IC封裝具有兩個堆疊IC晶粒,其中第一晶粒直接耦合到金屬化結構,並且堆疊在第一晶粒頂部的第二晶粒經由引線鍵合連接來連接到金屬化結構。IC晶粒經由金屬化結構的內部金屬層彼此耦合。通孔被用於耦合到內部金屬層。藉由穿過基板的內部金屬層來佈線,可以縮短總連接長度,這進而減少與連接相關聯的電阻和電感。降低的電阻和電感減少與電阻和寄生電感相關聯的損耗。
在解決具有堆疊晶粒引線鍵合連接的IC封裝的示例性細節(其中堆疊晶粒之間的連接長度藉由穿過金屬化結構的內部金屬層來佈線而縮短、且具有隨之而來的在電阻和電感方面的減小)之前,參考圖1A-1C提供了一般電路板和一般堆疊晶粒引線鍵合連接的概覽。下文參考圖2A開始論述具有堆疊晶粒引線鍵合連接的IC封裝,其中堆疊晶粒之間的連接長度藉由穿過金屬化結構的內部金屬層來佈線而縮短。
就此而言,圖1A是示例性背板或電路板100的方塊圖,其上具有包括經由焊料凸塊和引線連接鍵合來連接到電路板100的多IC晶片封裝的元件。具體地,電路板100可以由基板(諸如嵌入式跡線基板(ETS)、半加成製程(SAP)基板(具有或沒有底漆)、經修改的SAP(mSAP)基板等)來形成。
電路板100可以是較大的計算設備102的一部分,並且更具體地,可以是行動計算裝置的一部分。因此,電池104可位於電路板100上(或在Y軸方向的上方),並且經由金屬線108耦合到電源管理積體電路(IC)(PMIC)106。就此而言,電路板100可包括或是金屬化結構。PMIC 106可以包括開關式電源電路110和一或多個電感器112(示出一個)和一或多個電容器114(示出一個)。
多IC晶粒封裝116經由一或多個觸點耦合到金屬線108,在示例性態樣中,該觸點可以是焊料凸塊118。多IC晶粒封裝116可以包括第一IC晶片或晶粒120和以毗鄰的背靠背佈置安裝在第一晶粒120上的第二IC晶片或晶粒122。在該上下文中,背靠背意謂每個相應的IC晶粒120、122的輸入/輸出元件位於經組合的組裝件的相對側,而不是其將能夠直接彼此連接的面對面。作為進一步的參考,第二IC晶粒122可以位於第一IC晶粒120的上方(在Y軸方向上),第一IC晶粒120進而位於電路板100的上方(同樣在Y軸方向上)。第二IC晶粒122經由引線鍵合連接124(1)-124(X)來連接到電路板100。
如同樣在圖1B中可見,引線鍵合連接124(1)-124(X)可以耦合到電路板100上的相應的觸點焊盤126(1)-126(X)。觸點焊盤126(1)-126(X)可經由電路板100的金屬化結構132內的金屬線的頂部或第一金屬層130(例如,M0)中的導體128(1)-128(X)來連接到第一IC晶粒120上的焊料凸塊118(或其他輸入/輸出元件)。金屬線108亦可以位於電路板100的金屬化結構132中,並且可以位於不同的金屬層134(例如,M1)中。一或多個附加金屬層136(例如,M2-M8,僅示出一個)亦可存在於金屬化結構132中。介電材料138可分離金屬層130、134、136並且金屬層130、134、136可由通孔140來互連。電路板100可以經由附加觸點142(其可以是焊料凸塊等)來耦合到計算設備102內的背板或其他結構(未圖示)。
在實踐中,如圖1C中可見,大部分觸點焊盤126(1)-126(X)鄰近金屬化結構132的遠端邊緣144來放置。注意,圖1C未圖示引線鍵合連接124(1)-124(X)。觸點焊盤126(1)-126(X)的此種放置因變於設計約束,該等設計約束要求大部分頂部或第一金屬層130被用於與電路板100相關聯的各種其他元件或元件。在典型的佈置中,觸點焊盤126(X-N)至126(X)(如圖1C中所示)可為約兩毫米(2 mm)至幾乎三(3)mm(例如,如所圖示的,觸點焊盤126(Q)為1.95 mm至觸點焊盤126(X-N)為2.6 mm)。因此,在頂部或第一金屬層130中可能存在從遠端觸點焊盤126(1)-126(X)延伸回到焊料凸塊118的導體146(1)-146(X)(一般如圖1B中的箭頭148所示)。引線鍵合連接124(1)-124(X)的長度至少與導體146(1)-146(X)的長度相同,並且隨所遍歷的附加垂直距離增加一些距離而可能更大,該距離在一些情形中可能是不小的。相應地,信號從第二IC晶粒122上的輸入/輸出行進的路徑經過相應的引線鍵合連接124、經過觸點焊盤126、隨後經由導體146返回到第一IC晶粒120上的焊料凸塊118。由此,在最小的情況下,給定信號行進的距離至少是相應導體146的長度的兩倍。
就本文中所使用的術語「約」的範圍而言,該術語被定義為在百分之五(5%)之內。例如,約一百(100)個單位意謂在九十五(95)到一百零五(105)個單位之間。
因變於實體和幾何形狀,從第二IC晶粒122上的輸入/輸出經過相應的引線鍵合連接124、經過觸點焊盤126、隨後經由導體146返回到第一IC晶粒120上的焊料凸塊118的路徑的電阻與該路徑的距離成比例。電阻越高,經由熱量產生的能量損耗就越大。儘管在一些上下文中,熱量產生和能量損耗可能不很重要,但具體地對於行動計算設備而言,不必要的能量損耗是不合乎期望的,因為其可能縮短電池壽命並且使使用者體驗降級。進一步地,從第二IC晶粒122上的輸入/輸出經過相應的引線鍵合連接124、經過觸點焊盤126、隨後經由導體146返回到第一IC晶粒120上的焊料凸塊118的路徑的電感同樣地與該路徑的距離成比例。路徑的電感可導致反射損耗(亦即,從目的地反射回到傳送源的能量)。此類反射損耗可能使信號品質降級,同時導致不必要的能量損耗。相應地,此類反射損耗是不合乎期望的。
本案的示例性態樣提供了金屬化結構上的多晶片封裝,其中從封裝中的上晶粒到電路板的引線鍵合連接比一般佈置短得多。藉由經由金屬化結構內的內部金屬層(例如,M1)來佈置從連接到引線鍵合連接的觸點焊盤到下晶粒的連接,較短的引線鍵合連接是可能的。內部金屬層一般不具有與頂部金屬層相同的設計約束,並且相應地,到下晶粒的觸點的路徑可以更直接。縮短引線鍵合連接和從觸點焊盤到下晶粒的路徑降低了該路徑的電阻和電感,從而提高效能並且減少能量損耗。
圖2A圖示了金屬化結構202上的多IC晶片封裝200的橫截面側視圖,其可以是根據本案的示例性態樣的具有堆疊晶粒引線鍵合連接的電路板。圖2B圖示了圖2A的金屬化結構202的佈線佈置的俯視圖。第一IC晶片或晶粒204位於金屬化結構202上,並且第二IC晶片或晶粒206位於第一IC晶片或晶粒204上並且毗鄰於第一IC晶片或晶粒204。第二IC晶粒206可以位於第一IC晶粒204的上方(在Y軸方向上),第一IC晶粒120進而位於金屬化結構202的上方(同樣在Y軸方向上)。
金屬化結構202可以由基板(諸如ETS、SAP基板(具有或沒有底漆)、mSAP基板等)來形成,並且可以包括外部觸點208,外部觸點208可以是焊料凸塊等並且被配置成將IC封裝200耦合到背板或另一系統級結構。金屬化結構202可包括複數個金屬層210(0)-210(N)(例如,金屬層M0-M#N)。如本文所使用的,該等金屬層210(0)-210(N)被認為是在金屬化結構202「內」,因為其位於金屬化結構202的界限內。M0-M#N命名在業內是普遍的,並且在典型結構中,‘N’可以是三個或四個(3或4),儘管N可以更大而不脫離本案的範圍。參照Y軸,較低的數位在較高的數位的上方,以使得金屬層210(N)有時被稱為底部金屬層並且金屬層210(0)亦被稱為頂部金屬層,但其皆在金屬化結構202「內」。亦可以使用像「第一」和「第二」等的序數名稱而不脫離本案的範圍,但為了便於相對於圖2A來參照,將繼續使用頂部和底部。外部觸點208可被耦合到金屬層210(N)。金屬層210(0)-210(N)可以包括佈置成形成電連接的金屬跡線或導體,並且可以經由一或多個通孔212(1)-212(V)來彼此耦合。通孔212(1)-212(N)亦被認為是在金屬化結構202「內」,因為其位於金屬化結構202的界限內。在一些情形中,給定的通孔212可垂直地連接(例如,在Y軸方向)毗鄰的金屬層210(0)-210(N)(例如,通孔212(1)互連金屬層210(N)和金屬層210(1)),並且在其他實例中,給定的通孔212(2)可將頂部金屬層210(0)垂直地連接到底部金屬層210(N)。在存在多於三個金屬層的情況下,其他排列是可能的(例如,連接210(0)到210(4),跳過210(1)和210(2),但亦連接到210(3)等)。介電材料214可將金屬層210(0)-210(N)彼此分離。金屬化結構202可具有外部邊緣216(例如,相對於X-Z平面),並且第一IC晶粒204可以在外部邊緣216的內部間隔開。
第一IC晶粒204可包括下側或主動側219上的互連或觸點218,其將第一IC晶粒204內的內部電路系統及/或內部金屬跡線(未圖示)耦合到頂部金屬層210(0)。內部電路系統和金屬痕跡可被包封在模塑材料等中,這是很好理解的。在示例性態樣中,第一IC晶粒204處於倒裝晶片配置中,並且焊球220可以存在於觸點218和頂部金屬層210(0)之間。在示例性態樣,第一IC晶粒204可以是具有合適的電路系統的數據機或應用程式處理器。
第二IC晶粒206可包括由模塑材料等包封的內部電路系統及/或內部金屬跡線,這是很好理解的。外部觸點221可以位於第二IC晶粒206的主動表面或上表面222上(在Y軸方向上)。第二IC晶粒206可以位於第一IC晶粒204的上方,並且可以置於與第一IC晶粒204的背靠背佈置。亦即,由第二IC晶粒206的包封材料所形成的被動或下表面224可毗鄰並擱置在第一IC晶粒204的被動或上表面226上,其中被動或上表面226由第一IC晶粒204的模塑材料來形成。在示例性態樣中,第二IC晶粒206可以是包含記憶體電路系統的記憶體晶粒。
引線鍵合連接228(1)-228(X)可以從第二IC晶粒206上的外部觸點221延伸到金屬化結構202上的觸點焊盤230(1)-230(X)(在圖2B中更好地看到)。觸點焊盤230(1)-230(X)耦合到第一金屬層210(0)。
與一般封裝(例如,諸如圖1A-1C中所示的封裝)形成對比,本案的示例性態樣不排他性地使用頂部金屬層210(0)來將觸點焊盤230(1)-230(X)連接到觸點218。相反,如圖2A中所示,耦合到觸點焊盤230(1)-230(X)的通孔212將頂部金屬層210(0)連接到內部金屬層(諸如金屬層210(1))。隨後,相應的內部金屬跡線232(1)-232(X)耦合到耦合回頂部金屬層210(0)的其他通孔212。藉由佈置穿過通孔和內部金屬層(諸如金屬層210(1))的連接,該連接繞過頂部金屬層210(0)中的任何結構或「活動」。此類旁路允許觸點焊盤230(1)-230(X)位於更靠近第一IC晶粒204的位置。在一些實現中,此類放置意謂觸點焊盤230(1)-230(X)位於金屬化結構202的外部邊緣216的內部(例如,間隔開)(參見圖2B)。
藉由將觸點焊盤230(1)-230(X)放置在更靠近第一IC晶粒204的位置,縮短了信號在第二IC晶粒206和第一IC晶粒204之間行進的整體路徑長度。由於該路徑的電阻和電感與路徑長度成比例,因此縮短路徑長度降低了電阻和電感,從而相應地改進效能並減少能量損耗。在示例性態樣中,引線鍵合連接228(1)-228(X)的長度為一(1)mm。順便一提,不僅長度縮短了,其可能變得更加統一。經由比較,通孔212約為0.025 mm,因此允許兩個通孔212、引線鍵合連接228和金屬跡線232,整體路徑距離可以約為2.05 mm。相比之下,一般系統可具有約為3.9-5.2 mm的整體路徑(引線鍵合連接124加上金屬導體146)。同樣,經由比較,電阻可從約500毫歐(mΩ)變化到280 mΩ,這可對應於2100兆赫(MHz)時導體損耗的約0.1分貝(dB)減小。類似地,可將電感從約2奈米亨利(nH)減小到1.2 nH,這可對應於2100 MHz時反射損耗的約7.3 dB減小。其他頻率可導致不同的節省。同樣,該等比較基於2.6 mm的初始引線鍵合連接124的長度。與較長的引線鍵合連接的比較將導致更多的節省。
儘管本文參照特定的軸使用像「上方」、「下方」、「較上」、「較下」、「頂部」和「底部」的術語,但應當瞭解,此類術語被用於輔助讀者理解相關聯的附圖內的元件的相對位置,並且不意欲施加絕對取向。例如,無論包含IC封裝200的行動電話是面朝下、面朝上、垂直持握或水平持握,晶粒204、206的相對位置將保持相同。然而,在該等不同的位置的每一者中,像「上」、「下」、「較上」或「較下」的術語可以改變。應當瞭解,序數標籤(例如,第一、第二、第三等)可等效地用於代替此類術語。
本案的堆疊晶粒引線鍵合連接的益處(例如,路徑縮短,以及電阻和電感的相應降低)不限於兩個堆疊晶粒。相反,如圖3A和3B所圖示的,三個(或更多個)堆疊晶粒可以利用本案的堆疊晶粒引線鍵合連接,並且在降低的電阻和電感方面具有相應的改進。
就此而言,圖3A圖示了根據本案的示例性態樣的具有堆疊晶粒引線鍵合連接的金屬化結構上的三晶片封裝的橫截面側視圖,而圖3B圖示了圖3A的金屬化結構的佈線佈置的俯視圖。具體地,圖3A圖示了IC封裝300,並且尤其是具有金屬化結構302的多堆疊晶粒IC封裝,其可以是電路板、第一IC晶片或晶粒304和第二IC晶片或晶粒306。第二IC晶粒306可以位於第一IC晶粒304的上方(在Y軸方向上),第一IC晶粒304進而位於金屬化結構302的上方(同樣在Y軸方向上)。第三IC晶粒307可位於第二IC晶粒306的上方並擱置於其上。
金屬化結構302可以由基板(諸如ETS、SAP基板(具有或沒有底漆)、mSAP基板等)來形成,並且可以包括外部觸點308,外部觸點208可以是焊料凸塊等並且被配置成將IC封裝300耦合到背板或另一系統級結構。金屬化結構302可包括複數個金屬層310(0)-310(N)(例如,金屬層M0-M#N)。M0-M#N命名在業內是普遍的,並且在典型結構中,‘N’可以是三個或四個(3或4),儘管N可以更大而不脫離本案的範圍。參照Y軸,較低的數位在較高的數位的上方,以使得金屬層310(N)有時被稱為底部金屬層並且金屬層310(0)亦被稱為頂部金屬層。同樣,亦可以使用像第一和第二的序數名稱,但為了便於相對於圖3來參照,將使用頂部和底部。外部觸點308可被耦合到金屬層310(N)。金屬層310(0)-310(N)可以包括佈置成形成電連接的金屬跡線或導體,並且可以經由一或多個通孔312(1)-312(V)來彼此耦合。在一些情形中,給定的通孔312可以垂直地連接(例如,在Y軸方向上)毗鄰的金屬層310(0)-310(N)(例如,通孔312(1)互連金屬層310(N)和金屬層310(1)),並且在其他實例中,給定的通孔312(2)可以將頂部金屬層310(0)垂直地連接到底部金屬層310(N)。在存在多於三個金屬層的情況下,其他排列是可能的(例如,連接310(0)到310(4),跳過310(1)和310(2),但亦連接到310(3)等)。介電材料314可將金屬層310(0)-310(N)彼此分離。金屬化結構302可具有外部邊緣316(例如,相對於X-Z平面),並且第一IC晶粒304可以在外部邊緣316的內部隔開。
第一IC晶粒304可包括下側或主動側319上的互連或觸點318,其將第一IC晶粒304內的內部電路系統及/或內部金屬跡線(未圖示)耦合到頂部金屬層310(0)。內部電路系統和金屬痕跡可被包封在模塑材料等中,這是很好理解的。在示例性態樣中,第一IC晶粒304處於倒裝晶片配置中,並且焊球320可以存在於觸點318和頂部金屬層310(0)之間。在示例性態樣中,第一IC晶粒304可以是具有合適的電路系統的數據機或應用程式處理器。
第二IC晶粒306可包括由模塑材料等包封的內部電路系統及/或內部金屬跡線,這是很好理解的。外部觸點321可以位於第二IC晶粒306的主動表面或上表面322上(在Y軸方向上)。第二IC晶粒306可以位於第一IC晶粒304的上方,並且可以置於與第一IC晶粒304的背靠背佈置。亦即,由第二IC晶粒306的包封材料所形成的被動或下表面324可毗鄰並擱置在第一IC晶粒304的被動或上表面326上,其中被動或上表面326由第一IC晶粒304的模塑材料來形成。在示例性態樣中,第二IC晶粒306可以是包含記憶體電路系統的記憶體晶粒。
引線鍵合連接328(1)-328(X)可以從第二IC晶粒306上的外部觸點321延伸到金屬化結構302上的觸點焊盤330(1)-330(X)(在圖3B中更好地看到)。觸點焊盤330(1)-330(X)耦合到第一金屬層310(0)。
耦合到觸點焊盤330(1)-330(X)的通孔312將頂部金屬層310(0)連接到內部金屬層(諸如金屬層310(1))。隨後,相應的內部金屬跡線332(1)-332(X)耦合到耦合回頂部金屬層310(0)的其他通孔312。藉由佈置穿過內部金屬層(諸如金屬層310(1))的連接,該連接繞過頂部金屬層310(0)中的任何結構或「活動」。此類旁路允許觸點焊盤330(1)-330(X)位於更靠近第一IC晶粒304的位置。在一些實現中,此類放置意謂觸點焊盤330(1)-330(X)位於金屬化結構302的外部邊緣316的內部(例如,間隔開)(參見圖3B)。
類似地,第三IC晶粒307可包括由模塑材料等包封的內部電路系統及/或內部金屬跡線,這是很好理解的。外部觸點340可以位於第三IC晶粒307的主動表面或上表面342上(在Y軸方向上)。第三IC晶粒307可以位於第二IC晶粒306的上方。在示例性態樣中,第三IC晶粒307可以是包含記憶體電路系統的記憶體晶粒。
引線鍵合連接344(1)-344(Y)可以從第三IC晶粒307上的外部觸點340延伸到金屬化結構302上的觸點焊盤346(1)-346(Y)(在圖3B中更好地看到)。觸點焊盤346(1)-346(Y)耦合到第一金屬層310(0)。
耦合到觸點焊盤346(1)-346(Y)的通孔312將頂部金屬層310(0)連接到內部金屬層(諸如金屬層310(1))。隨後,相應的內部金屬跡線348(1)-348(Y)耦合到耦合回頂部金屬層310(0)的其他通孔312。藉由佈置穿過內部金屬層(諸如金屬層310(1))的連接,該連接繞過頂部金屬層310(0)中的任何結構或「活動」。此類旁路允許觸點焊盤346(1)-346(Y)位於更靠近第一IC晶粒304的位置。在一些實現中,此類放置意謂觸點焊盤346(1)-346(Y)位於金屬化結構302的外部邊緣316的內部(例如,間隔開)(參見圖3B)。
如同圖2A和2B的IC封裝200一樣,IC封裝300中的觸點焊盤330、346的移動縮短了信號的路徑,並且相應地減小了電阻和電感,從而減少了能量損耗並且改進了效能。
圖4是圖示用於製造具有堆疊的引線鍵合連接的多晶片封裝(例如,IC封裝200或300)的示例性程序400的流程圖。程序400始於形成具有頂部金屬層210(0)、310(0)和內部金屬層210(1)、310(1)的基板或金屬化結構202、302,其中頂部金屬層210(0)、310(0)中的觸點焊盤230、330經由通孔212、312連接到內部金屬層210(1)、310(1)(方塊402)。程序400繼續於經由引線鍵合連接228、328來將IC晶粒204、304連接到觸點焊盤230、330(方塊404)。下文參考圖6A-12D提供關於形成各種類型的金屬化結構202、302的更多細節,以及關於如何相對於金屬層在其中形成通孔的細節。

其他主設備和從設備可以連接到系統匯流排1308。如圖13中所圖示的,作為實例,該等設備可以包括記憶體系統1312、一或多個輸入設備1314、一或多個輸出設備1316、一或多個網路周邊設備1318,以及一或多個顯示控制器1320。(諸)輸入設備1314可以包括任何類型的輸入設備,包括但不限於輸入鍵、開關、語音處理器等。(諸)輸出設備1316可以包括任何類型的輸出設備,包括但不限於音訊、視訊、其他視覺指示器等。網路介面設備1318可以是被配置成允許往來於網路1322的資料交換的任何設備。網路1322可以是任何類型的網路,包括但不限於有線或無線網路、私有或公用網路、區域網路(LAN)、無線區域網路(WLAN)、廣域網路(WAN)、藍牙™網路,以及網際網路。(諸)網路介面設備1318可被配置成支援所期望的任何類型的通訊協定。記憶體系統1312可包括一或多個記憶體單元1324(0-N)。

圖14圖示了無線通訊設備1400的實例,該無線通訊設備1400可在圖13的基於處理器的系統中使用並且包括圖2A和3A的封裝。作為實例,無線通訊設備1400可以包括或設在任何上述設備中。如圖14中所示,無線通訊設備1400包括收發機1404和資料處理器1406。資料處理器1406可包括記憶體(未圖示)以儲存資料和程式碼。收發機1404包括支援雙向通訊的發射器1408和接收器1410。一般而言,無線通訊設備1400可包括用於任何數目的通訊系統和頻帶的任何數目的發射器及/或接收器。收發機1404的全部或一部分可被實現在一或多個類比IC、RF IC(RFIC)、混合信號IC等上。
發射器1408或接收器1410可以用超外差式架構或直接變頻式架構來實現。在超外差式架構中,信號在RF和基頻之間多級變頻,例如對於接收器1410而言,在一級中從RF到中頻(IF),隨後在另一級中從IF到基頻。在直接變頻式架構中,信號在一級中在RF和基頻之間變頻。超外差式以及直接變頻式架構可以使用不同的電路區塊及/或具有不同的要求。在圖14中的無線通訊設備1400中,發射器1408和接收器1410用直接變頻式架構來實現。
在發射路徑中,資料處理器1406處理要被傳送的資料並且向發射器1408提供I和Q類比輸出信號。在示例性無線通訊設備1400中,資料處理器1406包括數位類比轉換器(DACs)1412(1)和1412(2)以將由資料處理器1406產生的數位信號轉換成I和Q類比輸出信號(例如,I和Q輸出電流)以用於進一步處理。
在發射器1408內,低通濾波器1414(1)、1414(2)分別對I和Q類比輸出信號進行濾波以移除由在前的數位類比轉換引起的不期望鏡頻。放大器(AMPs)1416(1)、1416(2)分別放大來自低通濾波器1414(1)、1414(2)的信號並且提供I和Q基頻信號。升頻轉換器1418經由混頻器1420(1)、1420(2)用來自發射(TX)本端振盪器(LO)信號產生器1422的I和Q TX LO信號來升頻轉換I和Q基頻信號,以提供經升頻轉換信號1424。濾波器1426對經升頻轉換信號1424進行濾波以移除由升頻轉換引起的不期望鏡頻以及接收頻帶中的雜訊。功率放大器(PA)1428放大來自濾波器1424的經升頻轉換信號1426,以獲得期望的輸出功率位準並提供發射RF信號。該發射RF信號被路由經過雙工器或開關1430並經由天線1432被發射。
在接收路徑中,天線1432接收由基地台傳送的信號並提供收到RF信號,該收到RF信號被路由經過雙工器或開關1430並被提供給低雜訊放大器(LNA)1434。雙工器或開關1430被設計成用特定的RX與TX雙工器頻率分隔來操作,使得RX信號與TX信號隔離。該收到RF信號由LNA 1434放大並且由濾波器1436濾波,以獲得期望的RF輸入信號。降頻轉換混頻器1438(1)、1438(2)將濾波器1436的輸出與來自接收(RX)LO信號產生器1440的I和Q RX LO信號(亦即,LO_I和LO_Q)進行混頻以產生I和Q基頻信號。I和Q基頻信號由AMP 1442(1)、1442(2)放大並且進一步由低通濾波器1444(1)、1444(2)濾波以獲得I和Q類比輸入信號,該I和Q類比輸入信號被提供給資料處理器1406。在該實例中,資料處理器1406包括類比數位轉換器(ADCs)1446(1)、1446(2)以將類比輸入信號轉換成要進一步由資料處理器1406處理的數位信號。
在圖14中的無線通訊設備1400中,TX LO信號產生器1422產生用於升頻轉換的I和Q TX LO信號,而RX LO信號產生器1440產生用於降頻轉換的I和Q RX LO信號。每個LO信號是具有特定基頻的週期性信號。發射(TX)鎖相迴路(PLL)電路1448從資料處理器1406接收時序資訊,並且產生用於調整來自TX LO信號產生器1422的TX LO信號的頻率及/或相位的控制信號。類似地,接收(RX)鎖相迴路(PLL)電路1450從資料處理器1406接收時序資訊,並且產生用於調整來自RX LO信號產生器1440的RX LO信號的頻率及/或相位的控制信號。
