چکیده
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 while the nonlinear error is less than 1.35%. The experimental results are given to demonstrate the proposed circuits.
