A Novel Low-Voltage Low-Power FGMOS and CMOS Resister-Based Current Mirror

Abstract

A new Floating gate metal oxide semiconductor (FGMOS) and a CMOS Resistor-based current mirror (RBCM) with very low voltage requirement at input and output voltage is presented in this paper. The proposed circuit employs two resistors arranged in a symmetrical configuration, one control circuit and FGMOS the resulting error in two resistors circuits is subtracted to each other, this property reduces error and improves precision. The circuit is designed and investigated by using Cadence virtuoso, EDA tool with 180 nm technology under supply voltage of 0.75 V. This circuit has the advantage of high output impedance, low input impedance, wide input swing, large output swing, high linearity which makes this circuit a preferred choice for high performance low-voltage, wide range of input voltage and low-power application. The simulation results show are quite motivating as this circuit offers extremely low input impedance of 370 $\Omega$, output impedance of 1 $7\mathrm{M}\Omega$ and power consumption of 150 $\mu$ A.
