Low-voltage differential voltage follower for WTA and fully differential applications
A low-voltage differential version of a high performance voltage follower is presented. The proposed circuit is very compact, and symmetric with respect to the input devices. Both differential input devices are enhanced by local shunt feedback, increasing the gain and, thus, reducing the output resistance for higher precision. The circuit has proved useful as a winner-take-all (WTA) circuit. It...
متن کامل"The flipped voltage follower"-based low voltage fully differential CMOS sample-and-hold circuit
This paper presents the design and preliminary results of a full differential sample-and-hold circuit based on the "flipped voltage follower" (FVF) cell. The heart of this circuit is a fully differential low-voltage OTA based on FVF technique. The use of the FVF reduces the supply power requirements in the OTA. To overcome input sampling switches limitation imposed by the low supply voltage we ...
متن کاملVery low-voltage fully differential amplifier for switched-capacitor applications
A fully differential opamp suitable for very-low voltage switched-capacitor circuits in standard CMOS technologies is introduced. The proposed two stage opamp needs a simple low voltage CMFB switched-capacitor circuit only for the second stage. Due to the reduced supply voltage, the CMFB circuit is implemented using bootstrapped switches. Minor modifications allow to use chopper stabilization f...
متن کاملLow voltage Low Power Fully Differential Buffer
In this letter a useful CMOS fully-differential buffer topology is presented. The proposed solution, performing the common mode feedback (CMFB) operation, shows a rail-to-rail characteristic, so it is particularly suitable for low-voltage (± 0.75V) low-power (<400 μW) applications. The simulated results have shown excellent general performance, evaluated in terms of suitable figures of merit (F...
متن کاملAn Ultra High CMRR Low Voltage Low Power Fully Differential Current Operational Amplifier (COA)
this paper presents a novel fully differential (FD) ultra high common mode rejection ratio (CMRR) current operational amplifier (COA) with very low input impedance. Its FD structure that attenuates common mode signals over all stages grants ultra high CMRR and power supply rejection ratio (PSRR) that makes it suitable for mixed mode and accurate applications. Its performance is verified by HSPI...
