Design of a CMOS Fully Differential Switched-Opamp for SC Circuits at Very Low Power Supply Voltages
نویسندگان
چکیده
This paper presents a fully differential opamp desing based on the switched-opamp approach. The common mode feedback of the proposed opamp only works on the output stage in order to allow a fast turn-on. The opamp was designed in a 0.35 m CMOS technology and is able to operate from a single 1V supply.

Switched-Opamp: An Approach to Realize Full CMOS Switched-Capacitor Circuits at Very Low Power Supply Voltages
The implementation of analog CMOS circuits that operate in the very low power supply voltage range (1 V to 2 V) becomes more important nowadays. Most accurate filter circuits are designed in the switched-capacitor technique. The existing design techniques require, however, the on-chip generation of a higher voltage by means of a voltage multiplier. In this paper, a novel technique, derived from...

Demand for low-power low-voltage integrated circuits (ICs) has rapidly grown due to the increasing importance of portable equipment in all market segments including telecommunications, computers, and consumer electronics. The need for low-voltage ICs is also motivated by the new submicron CMOS technology scaling that requires all transistor' s gate-to-source (V GS) voltage to operate in less th...
متن کاملA Very Low Voltage 9th Order Linear Phase Baseband Switched Capacitor Filter (RESEARCH NOTE)
A very low voltage 9th order linear phase baseband switched capacitor (SC) filter has been designed to be used as part of a cellular GSM (Global System Mobile) receiver. A Gaussian-to-6dB filter of the order of seven is chosen and a second order function is added to reduce the group delay variations around. The filter uses a fully differential topology to increase the dynamic range and reduce t...

Portable electronic systems require low-voltage low-power building blocks. An important building block is an A/D converter. ∆Σ ADCs provide an efficient way of trading off speed for resolution. The switched opamp (SO) technique allows design of switched-capacitor (SC) circuits at very low supply voltage without the use of multithreshold technologies or voltage multipliers to drive the switches ...

A two stage sub-µW Inverter-based switched-capacitor amplifier-filter is presented which is capable of amplifying both spikes and local field potentials (LFP) signals. Here we employ a switched capacitor technique for frequency tuning and reducing of 1/f noise of two stages. The reduction of power consumption is very necessary for neural recording devices however, in switched capacitor (SC) cir...
