Abstract :
The author presents a procedure for synthesizing an MOS circuit with an approximately exponential voltage-current characteristic. Analysis of an infinite array of ideal MOSFETs yields mathematically convenient results, which guide the development of an algorithm for finite arrays of nonideal MOSFETs. Given a desired exponential function, the design algorithm determines the required MOSFET device sizes
