Abstract :
A new topology for translinear filters in CMOS IC technology is presented. This translinear filter is based on the exponential relation of passive PN-diodes in CMOS technology while the CMOS transistors only provide gain. From simulations, it is demonstrated that this topology leads to an improvement in high-frequency performance. Cut-off frequencies higher than 200 MHz with total harmonic distortion (THD) figures around 2% are reported.
