A compact low-voltage CMOS exponential current-to-voltage converter free from transconductance parameter matching between NMOS and PMOS is proposed. The circuit is composed of level shift circuits and current mirrors. The SPICE simulation results show a 27 dB linear range with a linearity error of less than 1 dB.
