Abstract
The design of a high-speed, high gain OTA in a digital 90nm CMOS technology is presented. The OTA uses the gain enhancement technique outlined in (Bult and Geelen, 1990) to increase the DC gain. The amplifier is fully differential an utilizes fully differential gain enhancement OTAs. The frequency response shows that 70dB DC gain and a unity gain frequency of 2.5GHz is achieved. The OTA draws 20mA from a 1.2V power supply.
