Title

A NOVEL LOW VOLTAGE, LOW POWER AND HIGH GAIN OPERATIONAL AMPLIFIER USING NEGATIVE RESISTANCE AND SELF CASCODE TRANSISTORS

Pages

  303-308

Abstract

 In this work, a low power, low voltage and high gain operational amplifier is proposed. For this purpose, a NEGATIVE RESISTANCE structure is used in parallel with output to improve the achievable gain. Because of using SELF CASCODE TRANSISTORS in the output, the proposed structure remains approximately constant in a relatively large output voltage swing causing an invariable gain. To evaluate the proposed method an OP AMP was designed in 0.18mm CMOS technology. The simulation results showed a gain of 84dB, unity gain bandwidth of 12.45MHz and phase margin of 81 degree, with 1V power supply and 1pF load capacitor.
