high-gain amplifier的用法和樣例：
例句
- The guard amplifier is a unity-gain amplifier with very high input impedance.
保護放大器是一個(gè)具有非常高輸入阻抗的單位增益放大器。 - To gain further bisymmetric baseband signals, the proposed transconductance stage is formed with a cross-coupled type.
之后經(jīng)過(guò)可變增益放大器將升頻后之訊號放大到功率放大器所要求之強度。
