A -80 dB HD3 opamp in 3.3 V CMOS technology using tail current compensation
The proposed unity gain configuration operational amplifier (opamp) uses a new tail current compensation method to linearize the input differential pair. The circuit, fabricated in a 0.35 /spl mu/m CMOS process, has HD3 less than -80 dB up to 10 MHz, and less than -60 dB up to 80 MHz input frequency...

| description | The proposed unity gain configuration operational amplifier (opamp) uses a new tail current compensation method to linearize the input differential pair. The circuit, fabricated in a 0.35 /spl mu/m CMOS process, has HD3 less than -80 dB up to 10 MHz, and less than -60 dB up to 80 MHz input frequency. The supply voltage is 3.3 V and signal amplitude is 1 V p-p. The opamp is well suited as a track and hold buffer. |
