Flash comparator
WebAn N -bit flash ADC comprises of a resistive ladder that contains 2 N resistors and 2 N -1 comparators. The reference voltage of each comparator is 1 least significant bit (LSB) higher than the one below it in … WebDither is used here to improve ADC linearity [20]. The seven flash comparators sample the ADC input (up to 6.6V pp,diff with V ref 2, Φ 2. D. SAR Comparator. The comparator is a critical block in terms of power, noise, speed, and reconfigurability. Fig. 4 shows the block diagram of the comparator. The integrators before the latch are ...

WebHence the flash comparators are “pipelined” into a quasi-serial process of 2-3 cycles. This has the benefit of allowing higher resolutions to be achieved without huge energy, but it imposes two penalties: sample rates cannot be as high as a pure Flash approach, and there is a latency of typically of 3 cycles. ... WebDec 21, 2024 · A 4-BIT flash-ADC is simulated in this work in 90 nm CMOS technology by altering the comparator structure. Two comparators are employed for analysis one is a comparator with cross-coupled inverters & other is a comparator with regenerative latch. Simulations are executed by varying the supply voltage & channel width for different …
WebIn this work, Flash ADC has been designed using two-stage operational amplifier as comparator, voltage divider circuit and priority encoder. The proposed prototype has been simulated with 2.8V supply voltage at 27°C. The simulation results for the design shows an overall power dissipation of 3.6947mW for flash ADC, 431.637μW for the comparator.
