Hysteresis pulse width modulation has different application because of its unmatched dynamic response and wide command tracking bandwidth. The various hysteresis modulation schemes are available in literature for multilevel inverter. The techniques are desired and compare the reference signal to obtain the adequate switching frequency, excellent dynamic response and high accuracy in steady state operation...
This paper presents a 0.5 V, 50 MS/s, 6 bit Flash ADC designed using 180 nm CMOS technology. To reduce the silicon area and power requirement, an inverter based comparator is used in the design. Low threshold MOSFETs are used for the ultra low voltage operation. A simple clock delaying technique and back to back inverters in the comparator have been used to increase the power efficiency and speed...
