Abstract
ICやLSI等の半導体デバイスは高圧の静電気によって破壊されたり、特性が劣化したりするため、静電気対策としてバリスタ等のサージ吸収素子が使用されている。バリスタを始めとするサージ吸収素子は浮遊容量成分や浮遊誘導成分を持つため、高速信号を扱う回路に適用すると信号を劣化させてしまう。浮遊容量と制御電圧・エネルギー耐量はトレードオフの関係にあるため、高速信号用途に対して特性のよいサージ吸収素子を適用できないという課題があった。
【解決手段】
上記目的を達成するために、本願発明に係るサージ吸収回路は、誘導素子等を利用してサージ吸収素子の浮遊容量成分の影響をキャンセルする。
【選択図】図7
Description
高圧サージが入出力端子101に入力すると、バリスタ103によって共通端子102に逃がされる。この結果、図1に示すサージ吸収回路を半導体デバイスの入出力端子に接続しておくと、半導体デバイスは高圧サージから保護されることになる。
となる誘導素子を用いれば、入力インピーダンスを信号ラインの特性インピーダンスに整合させることができる。なお、Z0はサージ吸収回路を挿入する信号ラインの特性インピーダンスである。ただし、(2)式の条件があるため、高周波ではやはり特性インピーダンスに整合させることができなくなり、バリスタの浮遊容量を小さくする必要があることに変わりはない。
本願発明の実施形態に係るサージ吸収回路の回路構成を図7に示す。図7において、11は入力端子、12は出力端子、13は共通端子、14は第一のサージ吸収素子、15は第二のサージ吸収素子、16は第二の誘導素子、17は第一の誘導素子である。
本願発明の実施形態に係るサージ吸収回路の回路構成を図12に示す。図12において、11は入力端子、12は出力端子、13は共通端子、14は第一のサージ吸収素子、15は第二のサージ吸収素子、16は第二の誘導素子、17は第一の誘導素子、18は容量素子である。
上記(8)式からも分かるように、サージ吸収素子の浮遊容量に対して、容量素子の容量Csを任意に選べるため、実施形態1で説明したサージ吸収回路よりも柔軟性の高い回路設計が可能となる。
上記(10)式からも分かるように、第一の誘導素子17が浮遊容量成分を持つ場合であっても、サージ吸収素子14及び14の浮遊容量成分と同時に第一の誘導素子17の浮遊容量成分の影響をキャンセルすることができる。
