A 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 کاملProposed Telescopic Op-Amp with Improved Gain
Before venturing further on the design of our operational amplifier, the first line of business is to determine the optimal topology for the given specifications. The factor that clearly stands out is the high dynamic range requirement of 85 db. Several topologies are given for this task, among these telescopic op-amp is selected. Compensation techniques are used with two stage topology of tele...
متن کاملCmos Based Current Feedback Op-amp with Improved Bandwidth
A current mode feedback operational amplifier designed using a complimentary MOS circuit technology has been discussed in this paper. A class AB amplifier has been used in the design and the design results in improvement of values of number of parameter when compared to the previously reported architecture. The circuit is designed using 0.35μm technology. Bandwidth of the presented architecture...
متن کاملGeometric Programming: a Tool for Cmos Op-amp Design
In this paper a new method for determining the component values and transistor dimensions for CMOS operational amplifiers (Op-Amps) is presented. As a wide variety of design objectives and constraints are Posynomial function of the design variables, the Optimization is done by Geometric Programming. As a consequence we can efficiently determine globally optimal trade-offs among competing perfor...
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-...
