Abstract
This paper presents a fully integrated low-power direct-conversion receiver for 5GHz wireless application. The IC was fabricated in a 0.18-μm CMOS technology. It combines LNA, mixer, integer-N frequency synthesizer, AGC loop, and low-pass channel-select filter. A newly proposed operational amplifier that can boost 35dB in voltage gain without consuming extra power is used in the channel-select filter under low-voltage and low-power requirement. Operating with a 1.5V supply, the power consumption of this receiver is 66mW.
