ABSTRACT
A low-voltage, low-power, high-gain and low-noise operational transconductance amplifier (OTA) by modifying conventional one is presented and analyzed. Design strategies are discussed for minimizing noise and increasing gain. The simulation results show that the open loop gain is improved from 68 dB to 74 dB and the input referred noise is also reduced from 926 to 475
. This amplifier operates at 0.8 V power supply voltage with a power consumption of 0.9 µW. All the simulations are obtained by using Hspice tool with 0.18 µm CMOS TSMC parameters.
