Abstract

A 2.1GHz, 1.3V, 5mW, fully integrated Q enhancement LC bandpass biquad programmable in peak gain, Q and f_o is implemented in 0.35μm standard CMOS. The Q tuning is through an adjustable negative conductance generator. Measured frequency tuning (through varactors) is 13% around 2.1GHz. The filter sinks 4mA from 1.3V providing a Q of 40 at 2.19GHz with 1dB compression DR of 38dB and SFDR of 33dB. The silicon area is 0.1mm².
