差分对管 meaning in English

differential pair tube

The other is the design of amplifier with constant trans - conductance ( gm ) rail - to - rail input stage . when common mode input voltage changes , it provides nearly constant - gm independent of input transistor operating region ( strong , moderate or weak inversion ) , and the quiet nods of the circuit for current addition and the output stage keep unchanged
当输入共模电压变化时,不管它的输入mos差分对管处于强反型区还是弱反型区,输入级的跨度保持不变,而且输入级后面的电流加法电路和输出级的静态工作点也不会随之改变。
