摘要: We present a section of second-order low distortion continuous-time filter employing MOSFETs operating in weak inversion. The idea is based upon the recently proposed log-domain approach used bipolar technology. Measured results from test chip fabricated 0.8? Bicmos process are presented. Chip power consumption 1?W and tuneable frequency range 100-10kHz.
