Title
A 1GHz-GBW operational amplifier for DVB-H receivers in 65nm CMOS
Abstract
The offer of information grows rapidly in mobile markets. The DVB-H standard as a part of DVB-T is an important carrier of information to a broad spectrum of consumers. New, cheap and robust receivers have to be developed, especially for handheld devices. We propose a high-speed operational amplifier for a low-pass filter in a direct conversion receiver. In order to integrate the receiver on a System on Chip, it is designed in 65nm low-power CMOS. The operational amplifier is a four-stage feed-forward nested Miller compensated fully differential operational amplifier with an AB output stage. A gain-bandwidth product of 1GHz and a gain of 58dB is reached. A load capacitance of 5pF can be driven at a phase margin of 62deg.
