This paper describes and compares some of the most energy and area efficient self-calibration techniques reported over the past years. Additional techniques used to further improve power dissipation are briefly described as well. A robust mixed-signal self-calibration technique is proposed, in which, the multi-bit first stage in the ADC is calibrated without requiring any modifications, as long as...
A 6th order Chebyshev type I low pass filter applied in zero-IF wireless receivers, implemented in 0.18 ??m CMOS technology is introduced, this filter is realized with leapfrog structure, has an attenuation of 30 dB at 5.25 MHz, less than 1 dB in-band ripple, 25 nV/sqrt(Hz) input referred noise at 5 kHz, and draws 2.6 mA from 1.8 V supply. By employing frequency calibration circuit, the cut-off frequency...
