چکیده
Two bulk-driven CMOS (Complementary Metal Oxide Semiconductor) operational amplifier (op-amp) designs for electrocardiogram (ECG) application are presented and compared in this paper. Both op-amps based on two-stage amplification, where differential input is the first stage, while additional DC gain second stage. Different compensation techniques were integrated each op-amp design. Standard Miller was used parallel with The novelty of that it utilizes negative between node output stag, standard purpose work to compare gain, phase margin (PM) unit frequency (UGF) obtained through different simulated strategies test results. using 0.25 μm technology. simulation results model libraries from Tanner EDA tools, operating a single rail +0.8V power supply.

متن کاملA Negative Conductance Voltage Gain Enhancement Technique for Low Voltage High Speed CMOS Op Amp Design
A new circuit technique for voltage gain enhancement in CMOS op amp design suitable for low voltage and high speed operation is presented in this paper. A negative conductance is used to cancel the positive output conductance of an amplifier thereby reducing the total equivalent output conductance and increasing the voltage gain of the amplifier. The negative conductance is derived from the out...

متن کاملDesign and Performance analysis of Low power CMOS Op-Amp
This paper proposes a low power CMOS operational amplifier which operates at 1.8 V power supply. The unique behavior of the MOS transistors in sub-threshold region not only allows a designer to work at low input bias current but also at low voltage. While operating the device at weak inversion results low power dissipation but dynamic range is degraded. Designing of two-stage Op-Amp is a multi-...
