Abstract
The circuit is designed for improving the relationship between input voltage and output current of the MOS transistor, which is square function. This circuit can be used instead of n-channel MOSFET at once. The circuit consists of MOSFET, which acts as a voltage receiver. The source of MOSFET is connected to current control part which consist of bipolar transistors. The exponential characteristic of bipolar transistor is used to solve the square function of MOSFET that base on concept of log and anti-log circuit. The experimental results of simulation are agreed with the implemented circuit.
