Differential to single-ended chip energy storage capacitor

Is a passive switched-capacitor single-ended-to-differential-converter a front-end?

Abstract: This paper proposes a passive switched-capacitor single-ended-to-differential-converter (SDC) as a front-end of a differential SAR ADC to enable digitization of single-ended signals.

Can merged capacitor switching improve the configuration of single-ended/differential input modes?

An improved merged capacitor switching technique is proposed to realize the configuration of the single-ended/differential input modes. Compared to active single-ended-to-differential converter solutions or single-ended SAR ADCs, the proposed solution achieves a smaller chip area and better power efficiency.

Can a single-ended-to-differential-converter be a front-end of a differential SAR a?

This paper proposes a passive switched-capacitor single-ended-to-differential-converter (SDC) as a front-end of a differential SAR ADC, such that it can convert single-ended input signals. As the SDC is passive, the overall solution is power-efficient compared to active SDC solutions, and is especially suitable for lower/medium resolutions.

What is a differential switched-capacitor amplifier?

The differential switched-capacitor amplifier employs an op amp voltage cancellation technique without requiring its output to slew to analog ground each time the amplifier is reset. Additionally, the circuit topology is very insensitive to low op amp gain and allows to attain 9-bit linearity.

Can a single-ended SAR ADC reduce parasitic capacitors effects?

In this work, a novel switching scheme for single-ended SAR ADCs is presented. The proposed scheme uses a symmetrical structure to decrease parasitic capacitors effects. The first two bits are resolved without consuming any energy which significantly improves DAC’s power consumption. Also, the proposed scheme is consuming zero reset energy.

Are single-ended SAR ADC drivers energy-efficient?

To gain the advantages of fully-differential SAR ADCs, single-ended to differential ADC drivers can be utilized which results in additional cost in area and power consumption . Designing an energy-efficient single-ended SAR ADC is more challenging but requisite for high-performance CMOS image sensors.
