如图2所示,偏置电源模块23从电源垫6接收电源电压,并以稳压电源电压和/或一个或多个受控偏置电流为微波放大器21供电。微波放大器21还从接地垫8接收接地电压。
保护电感器22电连接在巴伦50的初级部分51和接地垫8之间,并且用于保护微波放大器21免受电气过应力。附加地或替代地,微波放大器21可以利用本文公开的任何保护结构来实现。在某些实施方式中,微波放大器21是毫米波放大器。
图3是根据一个实施例的毫米波放大器150的示意图。毫米波放大器150包括巴伦125,一对输入电感器126,放大电路127,一对源电感器128,第一交叉耦合电容器131和第二交叉耦合电容器132。
尽管毫米波放大器150示出了具有防止电气过应力的保护的放大器的一个实施例,但是本文的教导适用于以多种方式实现的放大器。此外,本文的教导还可应用于处理来自巴伦的差分RF信号的其他类型的RF电路。
如图3所示,巴伦125包括初级部分135,初级部分135从RF信号板101接收RF信号。初级部分135电连接在RF信号板101和由接地垫提供的接地电压之间(图3中未示出)。巴伦125还包括次级部分136,次级部分136输出差分RF信号,该差分RF信号通过一对输入电感器126提供给放大电路127。
在所示的实施例中,放大电路127包括第一放大场效应晶体管(FET)141和第二放大FET 142。另外,输入电感器126包括第一输入电感器137和第二输入电感器138。图3中,第一放大FET 141的栅极通过第一输入电感器137电连接到巴伦125的次级部分136的第一端,而第二放大FET142的栅极通过第二输入电感器138电连接到巴伦125的次级部分136的第二端。
包括第一输入电感器137和第二输入电感器138有助于保护第一放大FET 141和第二放大FET 142不受损坏。例如,第一输入电感器137和第二输入电感器138可用于阻止或阻止高频电流到达FET的栅极并引起电压累积。
第一放大FET 141和第二放大FET 142可以以多种方式实现,例如使用金属氧化物半导体晶体管(MOS),FinFET晶体管和/或化合物半导体晶体管,例如高电子迁移率晶体管(HEMT)。因此,本文的教导可适用于广泛的处理技术,包括但不限于硅工艺(例如,绝缘体上硅或SOI)和化合物半导体工艺(例如,氮化镓或GaN)。尽管示出了具有n型晶体管的示例,但是本文的教导也适用于具有p型晶体管或p型和n型晶体管的组合的放大器。此外,尽管示出了具有FET的示例,但是本文的教导也适用于用双极晶体管或FET和双极晶体管的组合实现的放大器。此外,本文的教导还可应用于处理来自巴伦的差分RF信号的其他类型的RF电路。
第一放大FET 141和第二放大FET 142可以具有任何合适的几何形状,例如该技术的最小沟道长度(以在微波频率下提供增强的性能)以及基于噪声系数(NF)约束选择的宽度。FET布局可以包括使用金属化彼此电连接的多指器件。在一个示例中,每个放大FET包括64个320nm宽度的指状物,以实现整个器件的18μm的宽度。但是,其他实施方式也是可能的。
如图3所示,一对源极电感器128包括电连接在第一放大FET 141的源极和接地电压之间的第一源极电感器143和电连接在第二放大FET 142的源极和接地电压之间的第二源极电感器144。

在一个示例中,共同接地垫将接地电压提供给巴伦125的初级部分135以及第一放大FET 141和第二放大FET 142的源极。
在第二示例中,第一接地垫向巴伦125的初级部分135提供第一接地电压,而第二接地垫向第一放大FET 141和第二放大FET 142的源极提供第二接地电压。在某些实施方式中,第一接地垫和第二接地垫使用去耦电路(诸如去耦电感器和/或反并联二极管)在芯片上连接。因此,本文的教导可应用于包括多个接地域的芯片接口,所述多个接地域在芯片上或芯片外耦合以实现期望的隔离量。

除了毫米波放大器160进一步包括保护电感器151之外,图4的毫米波放大器160类似于图3的毫米波放大器150。
包括保护电感器151有助于防止RF信号板101处的电气过应力事件。这种电气过应力事件不仅包括ESD事件,而且包括其他类型的过载,例如场感应的充电设备模型(FICDM)事件。例如,保护电感器151用作巴伦125的初级部分135的并联电感器,并用于在短时过应力事件期间减小过应力。
在某些实施方式中,保护电感器151电连接到巴伦125的初级部分135的中心抽头。

在图5中,毫米波放大器被表示为跨导增益元件,示意性地描绘为n型场效应晶体管(NFET)171。然而,毫米波放大器可以以任何合适的方式实现。尽管描述了偏置电源模块的一个实施例,但是毫米波放大器可以以多种方式接收功率。
在所示的实施例中,偏置电源模块200从电源垫(图5中未示出)接收电源电压VDD(例如0.9V)。偏置电源模块200还接收参考电压VREF(例如0.7V),该参考电压可以是带隙电压。此外,偏置电源模块200还接收参考电流Iref。参考电压VREF和参考电流Iref可以在芯片上、芯片外或其组合中产生。
如图5所示,偏置电源模块200包括第一控制环路,该第一控制环路将稳压电源电压(在该示例中,对应于Vdrain)设置为基本等于基准电压VREF。另外,偏置电源模块200包括第二控制环路,该第二控制环路可操作为控制通过跨导增益元件171的电流基本等于参考电流(Iref)。当用于偏置毫米波放大器时,偏置电源模块200紧密地控制毫米波放大器(示意性地表示为NFET 171)的供应电压和电流。
在一些实施例中,NFET 171对应于图3、4和6-9D的第一放大FET 141或第二放大FET 142之一。在某些实施例中,电源偏置块200的所示电路被复制以为差分毫米波放大器的输入晶体管对的每个晶体管提供稳定的电压和受控的偏置电流。例如,所描绘的电路的第一实例可用于偏置图3、图4和图6-9D的第一放大FET 141(其中NFET 171的第一实例对应于第一放大FET 141),而所描绘的电路的第二实例可用于偏置图3、4和6-9D的第二放大FET142(其中NFET 171的第二实例对应于第二放大FET142)。
在所示的实施例中,电源偏置块200还产生测试电流I测试,可以对其进行处理以验证所描绘的偏置电流控制环路的准确性。
图6是根据另一实施例的毫米波放大器250的示意图。毫米波放大器250包括巴伦125、第一交叉耦合电容器131、第二交叉耦合电容器132、第一输入电感器137、第二输入电感器138、第一放大FET 141、第二放大FET 142、第一源电感器143、第二源电感器144、第一保护电感器151(在此也称为电感器L1)、第二保护电感器152(在此也称为电感器L2)、电容器241、电阻器242、电压源243。
除了毫米波放大器250还包括第二保护电感器152、电容器241、电阻器242和电压源243之外,图6的毫米波放大器250类似于图4的毫米波放大器160。
如图6所示,第二保护电感器152电连接到巴伦125的次级部分136。在某些实施方式中,第二保护电感器152连接到次级部分136的中心抽头。第二保护电感器152可以具有任何合适的电感值,例如,至少150pH的电感。
第二保护电感器152在巴伦125的次级部分136与来自接地垫的接地电压之间与电容器241串联电连接。
在某些实施方式中,第一保护电感器151和/或第二保护电感器152可通过金属化选项连接到巴伦125。因此,第一保护电感器151和/或第二保护电感器152可以经由金属可编程以提供期望的额外钳位。
如图6所示,电压源242与电容器241并联电连接,并且可操作以控制到第一放大FET 141和第二放大FET 142的DC输入电压。在某些实施方式中,电压源242的电压电平由电源控制块的控制环路控制,从而提供对通过放大器250的偏置电流的控制。

第一钳位FET 261和第二钳位FET 262用作用于毫米波放大器270的放大FET的off-FET(例如,off-NMOS)嵌入式保护。例如,钳位FET可用于提供自FICDM保护。
在某些实施方式中,使用共享的多指布局来实现放大FET和相应的钳位FET。例如,布局的指状部的第一部分可以用于实现放大FET(例如,第一放大FET 141),而布局的指状部的第二部分可以用来实现钳位FET(例如,第一钳位FET 261)。
在另一个实施例中,输入有源器件可以使用GaAs或GaN HEMT器件实现用于高功率高频微波和毫米波应用,因为这些类型的技术在高频操作和噪声性能方面具有优势。在这样的实施方式中,栅极端子在一个方向或施加的电压极性上用作正向肖特基二极管,而在相反的方向上对负过应力引起的损坏敏感。为了解决这个限制,针对GaAs和/或GaN高电子迁移率晶体管(HEMT)器件例如图19或20的横截面的情况,实施了上述实现(例如,可以对应于诸如CMOS工艺的硅工艺中的实现)。

除了毫米波放大器440还包括保护电感器151以外,图9D的毫米波放大器440类似于图9C的毫米波放大器430。
图10是根据一个实施例的电感器和巴伦布局的示意图。电感器和巴伦布局包括巴伦531,位于位置534处的用于输入晶体管的一对源极电感器532,以及用于在位置534处保护该对输入晶体管的栅极的一对输入电感器533。尽管描述了金属化布局的一个实施例,本文的教导适用于以多种方式实现的巴伦和电感器。
图11是仿真结果的一个例子的曲线图,示出了在有和没有栅源钳位的情况下实现的毫米波放大器的比较。该图描述了两种情况下输入晶体管栅极电压与时间的关系。
图12是仿真结果的一个示例的曲线图,其示出了比较在具有和不具有耦合到巴伦的初级部分的保护电感器的情况下实现的毫米波放大器的比较。如图12所示,模拟的应力事件为5Amps。
图13是仿真结果的一个示例的曲线图,示出了比较在具有和不具有耦合到巴伦的初级和次级部分的保护电感器的情况下实现的毫米波放大器的比较。如图13所示,模拟的压力事件为5Amps。
图14是仿真结果的一个示例的图,其示出了比较在具有和不具有耦合至巴伦的初级和次级部分的栅极-源极钳位和保护电感器的情况下实现的毫米波放大器的比较。如图14所示,模拟的应力事件为5Amps。

图17是仿真结果的另一示例的曲线图,示出了比较具有和不具有耦合至巴伦的初级和次级部分的栅极-源极钳位和保护电感器的毫米波放大器的比较。
尽管图11-17展示了模拟结果的各种示例,但其他模拟结果也是可能的,包括取决于实现、应用和/或处理技术的结果。
图18A是耦合到接口网络并由保护元件保护的化合物半导体HEMT的一个实施例的示意图。在某些实现中,是增强模式HEMT(E-HEMT),当RF端口相对于地面发生负极性过应力时,该模式可能会失败。例如,HEMT的金属栅极和通道之间的界面可以用作肖特基二极管,该肖特基二极管在相反的方向受力而失效。
在此类应用中,RFIN端口可能仅需要在一个方向或一个极性上进行保护,例如,防止RF端口相对于地(GND)产生负极性过应力。此外,核心HEMT栅极-源极二极管可以处理正极性过应力。
图18B是HEMT的肖特基栅极二极管结构(例如图18的HEMT)的电压与电流特性的一个示例图。与高级CMOS相比,因为受保护的核心肖特基结可以具有较大的击穿电压(BV),例如15V或更高,因此设计余量通常更大。尽管图18B示出了二极管反向特性的示例,但其他结果也是可能的。
图19是具有集成保护的HEMT 600的一个实施例的横截面。HEMT采用III-V复合半导体技术(在此示例中为GaAs)制造。尽管示出了具有GaAs的示例,但是本文的教导可应用于其他处理技术,例如硅和GaN。
为了提供低电容过应力保护,可以在栅极和源极之间明确添加ESD保护组件(例如,参见具有栅极-源极保护的图18A的E-HEMT)。
附加地或可替代地,可以在多条纹布局内利用附加的栅极/漏极条来保护肖特基栅极。
例如,在所示的实施例中,HEMT 600被制造在未掺杂的GaAs衬底601上。另外,InGaAs沟道层602(包括二维电子气或2DEG区域)被形成在未掺杂的GaAs衬底601上。然后,在InGaAs沟道层602之上形成AlGaAs间隔层603,并且在AlGaAs间隔层603之上形成NAlGaAs层。
HEMT 600包括第一栅极区域611a,第二栅极区域611b,位于第一栅极区域611a和第二栅极区域611b之间的漏极区域613。栅极区域由金属形成,并且与金属-半导体界面和相应的肖特基二极管相关。HEMT 600还包括第一源极区612a和第二源极区612b,第一栅极区611a位于第一源极区612a和漏极区613之间,第二栅极区611b位于漏极区613和第二源极区612b之间。
为了保护HEMT 600,已经包括附加的晶体管指以提供与HEMT 600和保护HEMT共享的与保护栅区615、保护漏区617和源极区612b相关的保护HEMT。如图19所示,保护性HEMT的栅极以金属(后端金属化)连接到HEMT 600的源极,而保护性HEMT的漏极连接到HEMT 600的源极。
以这种方式实现HEMT 600可以在HEMT 600的栅极和源极之间提供一个集成的肖特基二极管。
图20是HEMT 700的另一实施例的横截面。如图20所示,在HEMT700的栅极和源极之间可以包括嵌入式保护区域和/或元件701。
尽管描绘了特定的层和材料,但是其他实施方式也是可能的。在一个示例中,省略了Si衬底,从而有利于使用碳化硅(SiC)衬底。
应用
采用上述方案的设备可以被实现为各种电子设备。电子设备的示例可以包括但不限于消费类电子产品、消费类电子产品的一部分、电子测试设备、通信基础设施应用程序等。此外,电子设备可以包括未完成的产品,包括用于通信、工业、医疗、汽车、雷达和航空航天应用的未完成产品。
结论
前述描述可以将元件或特征称为“连接”或“耦合”在一起。如本文所用,除非另有明确说明,否则“连接”是指一个元件/特征直接或间接地连接至另一元件/特征,并且不一定是机械地连接。同样地,除非另有明确说明,否则“耦合”是指一个元件/特征直接或间接地耦合至另一元件/特征,而不必机械地耦合。因此,尽管在附图中示出的各种示意图描绘了元件和组件的示例布置,但是在实际的实施例中可以存在附加的中间元件、设备、特征或组件(假设所描绘的电路的功能没有受到不利影响)。
尽管已经描述了某些实施例,但是这些实施例仅以示例的方式给出,并且不意图限制本公开的范围。实际上,本文描述的新颖的装置、方法和系统可以以各种其他形式来体现。此外,在不脱离本公开的精神的情况下,可以对本文描述的方法和系统的形式进行各种省略、替换和改变。例如,虽然以给定的布置呈现了公开的实施例,但是替代实施例可以执行具有不同组件和/或电路拓扑的类似功能,并且可以删除、移动、添加、细分、组合和/或修改某些元件。这些元素中的每一个都可以以各种不同的方式实现。可以将上述各种实施例的元件和动作的任何适当组合进行组合以提供其他实施例。因此,本发明的范围仅通过参考所附权利要求来限定。
尽管此处提出的权利要求以单一依赖项格式在美国专利商标局(USPTO)提出,但应理解,任何权利要求都可能依赖于之前相同类型的任何权利要求,除非明显在技术上不可行。
