Comparative Analysis of Compensation Techniques for improving PSRR of an OPAMP
نویسنده
چکیده
This el The operational amplifiers are the primary blocks of most of the analog systems and mixed-signal integrated circuits. In most electronic devices, ripple noise in supply line is unavoidable. Hence a robust noise performance at high frequencies is required. This performance regarding the stability of OPAMP improves with help of frequency compensation techniques. The different compensation techniques CMOS OPAMP are Miller compensation, Cascode compensation, Blakiewicz compensation and Tail compensation. These Compensation techniques provide PSRR and stability to the OPAMP. These techniques has been done at 180nm CMOS technology, simulation and result were carried out in Cadence Spectre EDA TOOL with 1.8v power supply.

approved: Gabor C. Temes This thesis describes compensation techniques for cascaded delta-sigma A/D converters (ADCs) and high-performance switched-capacitor (SC) circuits. Various correlated-double-sampling (CDS) techniques are presented to reduce the effects of the nonidealities, such as clock feedthrough, charge injection, opamp input-referred noise and offset, and finite opamp gain, in SC c...

In order to solve the stability problems and increase the PSRR performance of the Low Drop-out Voltage (LDO) a novel technique is presented. The main purpose of this work was to obtain a high PSRR, high power efficiency with a low load current. To achieve this, several techniques such as Nested Miller Compensation (NMC), Pole-Zero Tracking Frequency Compensation (PZTFC) and Single Miller Compen...

A frequency compensation technique for the improvement of unity gain bandwidth (UGB) and power supply rejection ratio (PSRR) of two stage operational amplifiers is presented in this paper. Performance of proposed op-amp is compared with classical miller compensated op-amp and op-amp proposed by G. Blakiewicz [13]. The technique exploits the triode mode operation of a MOSFET in the compensation ...
متن کاملMHz opamp - RC filter in 0 . 18 p m CMOS
Opamp gain: The main difficulty in building a very high frequency opamp-RC filter is achieving sufficient opamp gain at the filter comer frequency. With the transfer function used here, 34 dB opamp gain results in 1 dB peaking and 30 dB opamp gain results in 2 dB peaking at the comer frequency. (This includes overcoming a 2 dB reduction in loop gain due to capacitance at the opamp input.) A con...
متن کاملDigital Offset Calibration of an OPAMP Towards Improving Static Parameters of 90 nm CMOS DAC
In this article, an on-chip self-calibrated 8bit R-2R digital-to-analog converter (DAC) based on digitally compensated input offset of the operational amplifier (OPAMP) is presented. To improve the overall DAC performance, a digital offset cancellation method was used to compensate deviations in the input offset voltage of the OPAMP caused by process variations. The whole DAC as well as offset ...
