Abstract:
A gmC-filter in 120nm CMOS with a digital programmable gain and cut-off-frequency is presented. For this application a technique to enhance the linearity of a fully differential operational transconductance amplifier (OTA) is proposed. A filter of 3rd order with a cut-off-frequency between 235MHz and 285 MHz and a gain between 0dB and 5dB is implemented. The third harmonic distortion of this filter is -43dB for a 400mV peak-to-peak differential output signal for minimum gain and -48dB for maximum gain
