Abstract :
The design and performance of a switched-R-MOSFET-C filter is presented in this paper. The filter achieves -77dB THD using a 0.6V supply, and -90dB THD using a 0.8V supply, with a 0.6Vpp differential 2kHz sine input. High linearity at a low supply voltage is achieved by the use of duty-cycle controlled tuning inside a feedback loop
