Abstract
In this paper, a CMOS differential input, differential output amplifier is presented. This amplifier operates in class AB mode and exhibits high current drive capability. The circuit is designed and implemented in a UMC 1P-9M standard 90-nm CMOS technology. It provides fast settling response of 235 ns while powered with 2 V. The proposed amplifier operates on a wide input differential range with high linearity exhibiting a P-1 dB of 10 dB. The circuit exhibits a differential current-drive capability of 2.9 mA. The presented amplifier has high gain-bandwidth product of 94 MHz. This differential amplifier provides a CMRR of 89 dB.
