Abstract
The logarithmic and exponential function generator for analog signal processing is implemented with CMOS circuits operating in current mode and includes current mirrors connected to a square root function circuit and two current amplifiers. A third current amplifier utilizes a constant current input. The outputs of the current amplifiers are combined to provide the logarithmic and exponential functions.
