A Micropower Chopper - CDS Operational Amplifier
A low-power spur-free precision amplifier, which uses input chopping and correlated double sampling for demodulation, is presented. This circuit employs an AC coupling between the first and the second stage that removes the first stage offset without causing ripple. The input rail-to-rail circuit, fabricated in a mixed 0.18–0.5 m CMOS technology, operates with supply ranging from 1.8 V to 5 V. ...
متن کاملA Modular Operational Amplifier Design
This paper proposes a module of a high gain and high swing 2-stage amplifier. It is suitable for building a general operational amplifier in a modular fashion with various optional performances. The proposed module alone offers opened-loop voltage gain up to 124 dB and GBW of 10 MHz without loading conditions. To assemble a 124 dB voltage gain operational amplifier with load driving capacity of...
متن کاملTelevision-optical operational amplifier.
The advantages of negative feedback are well known in electronics and extensively used in the operational amplifier. The properties of such a system are nearly independent of the parameters in the forward branch of the system; they are only determined by external elements in the backward branch. An optical analog of such an operational amplifier is reported. The essential operations, amplificat...
متن کاملA ±2.45V-Swing CMOS Telescopic Operational Amplifier
A telescopic cascode opamp typically has a higher frequency capability and consumes less power than other topologies. The disadvantage of a telescopic opamp is severely limited output swing. In a conventional telescopic opamp shown in Figure 1, all transistors are biased in the saturation region. Transistors M1-M2, M7-M8 and the tail current source M9 must have at least Vds,sat to offer a good ...
متن کاملTitle: A Synthetic Microbial Operational Amplifier
Synthetic biology has created oscillators, latches, logic gates, logarithmically linear circuits, and load drivers that have electronic analogs in living cells. The ubiquitous operational amplifier, which allows circuits to operate robustly and precisely has not been built with biomolecular parts. As in electronics, a biological operational-amplifier could greatly improve the predictability of ...
