Comparator-based switched-capacitor pipelined analog-to-digital converter with comparator preset, and comparator delay compensation
We present a differential comparator-based switched-capacitor (CBSC) pipelined analog-to-digital converter (ADC) with comparator preset, and comparator delay compensation. Compensating for the comparator delay by digitally adjusting the comparator threshold improves the ADC resolution from 2.5-bit to 7.05-bit. The ADC is manufactured in a 90 nm CMOS technology, with a core area of 0.85 mm 9 0.3...
متن کاملComparator Design and Analysis for Comparator - Based Switched - Capacitor Circuits
The design of high gain, wide dynamic range op-amps for switched-capacitor circuits has become increasingly challenging with the migration of designs to scaled CMOS technologies. The reduced power supply voltages and the low intrinsic device gain in scaled technologies offset some of the benefits of the reduced device parasitics. An alternative comparator-based switched-capacitor circuit (CBSC)...
متن کاملComparator-Based Switched-Capacitor Delta-Sigma Modulation
In order to eliminate the use of operational amplifiers (opamps) in sampled-data systems and thus avoid several delicate tradeoffs involved with their design, a new class of switched-capacitor circuits based on comparators was reported. The novelty of this comparator-based switched-capacitor (CBSC) design method is the detection of a virtual ground condition rather than forcing it through feedb...

متن کاملComparison of OpAmp Based and Comparator Based Switched Capacitor Filter
Comparator based switched capacitor circuits provide an excellent opportunity to design sampled data systems where the virtual ground condition is detected rather than being continuously forced with negative feedback in Opamp based circuits. This work is an application of this concept to design a 1 order 330 KHz cutoff frequency Lowpass filter operating at 10 MHz sampling frequency in 0.13μm te...
