Abstract

In this paper, the design and experimental results of a fully-differential folded-cascode operational amplifier of transconductance (OTA) is presented. This active circuit is for the use in a low-pass modulator. The structure of the OTA is for obtaining a transition frequency of 1.0GHz. From the circuit synthesis, the OTA can handle the signals with the peak-to-peak amplitude of 300mV, and consumes 1.5mA from 1.2V supply. The OTA is fabricated in 130nm standard CMOS technology.
