Popis: A low-voltage, micro-power, low-noise, high-gain, high-output swing current mirror-based operational transconductance amplifier (OTA) is presented. The proposed OTA achieves high DC gain and output swing by the adoption of gain boosted current mirroring and self-cascoding techniques. From the simulation, the proposed OTA implemented on a 0.18 μm CMOS shows the DC gain up to 90 dB with a gain bandwidth of 700 KHz for a load capacitor of 1 pF and an output voltage swing of 600 mV. The OTA dissipates only 750 nW from 1.0 V supply.
