چکیده
A high gain, high frequency single stage CMOS op amp is designed and simulated. The authors used gain boosting technique and common mode feedback circuitry on a differential input/ouput 0.5μm CMOS amplifier. Results comprehend a DC gain of 110 dB, a unity-gain frequency superior to 300MHz associated with a phase margin in the range of 60 degrees. Good insensivity to temperature, voltage rail level (2.5V +/10%) and common monde input voltage variations has been demonstrated.
