Abstract :
In this paper we present an Ultra-Low Voltage Pseudo Floating-Gate Amplifier (ULVPFGA). The amplifier has high gain and high linearity for supply voltages down to 300mV. The amplifier is based on Pseudo Floating-Gate and in addition to gain, it offers frequency band adjustment. Both the low- and high-frequency cutoffs are controlled electronically using bias voltages through their bulk. The ULVPFGA enjoys low component spread and compactness, containing only small size transistors and capacitors suited for integration. We also show a second order section realized using the ULVPFGA. The simulations presented in this paper are valid for the 90nm CMOS transistor models from STM having a V DD equal to 1.2V and threshold voltage of 250mV.
