New Design of CMOS Current Comparator

High Speed Average Power CMOS Current Comparator

“…Circuit [9] pre-occupied with more number of MOS and Capacitors than any of the designs. In this paper we are comparing the results obtained by the proposed design with earlier published papers [6] and [8].…”

“…In the pre-decision state transistors M0 and M6 are closed and transistors M1, M9 and M7, M8 are open. When compared to the speed of [6], the speed of operation of the comparator [8] is well increased.…”

“…[8]. When compared to the earlier implemented [6] circuit, in [8] author had added two more additional MOS transistors M8 and M9. These two MOS transistors speed up the decision process happening in the circuit.…”

“…Below Figure 3., Shows the Power plot of the current comparator at +/-10uA. [8]. When compared to the earlier implemented [6] circuit, in [8] author had added two more additional MOS transistors M8 and M9.…”

“…Though the above circuit resolves the speed and power issue of [1], but it consumes more power and takes more response time than recently published approaches. Designs [6] [7] [8] had come up with high speed circuits , but when compared to proposed one those consume more power and slow in response. In 2010 author [9] had come up with a new approach a low input impedance current comparator using pulse width modulation.…”
