Low Voltage and High Gain Bandwidth Constant Current Source using 90nm CMOS Technology

Menka Zankyani

Abstract: Current source circuit is found as one of the basic element in designing of analog integrated and mixed mode circuits. In this paper a current source with low input impedance, high output impedance, and high gain is proposed. This current source circuit is designed by using seven n-type and four p-type MOSFETs. Simulation process of the proposed circuit is performed using 90nm CMOS technology. Input impedance, output impedance and accuracy are the most important parameters to observe the performance of the Current Source. The proposed current source circuit is operated at the supply voltage of 0.8V.
