—Compact, accurate and low-power analog CMOS circuits for current-mode division and pseudo-exponential function generation are presented, based on a new variable transresistance amplifier. Experimental results of the circuits fabricated in a 0.5-m 2P2M n-well CMOS process show better than 0.3% total harmonic distortion. Measured power is less than 0.22 mW(More)
A CMOS differential-mode exponential voltage-to-current converter is presented which is based on the approximated Taylor's series expansion. The proposed circuit has been fabricated in a 0.5µm N-well CMOS process. Experimental results show that the output dynamic range of the proposed differential-mode exponential voltage-to-current converter can be 15dB(More)
