Ageing Impact on a High Speed Voltage Comparator with Hysteresis

The impact of ageing on a high speed comparator with hysteresis in 65-nm CMOS technology using SPICE simulations is investigated. The comparator has been designed to offer immunity to single event transients. The most sensitive transistor was subjected to single events at manufacture time and after ageing, assuming a maximum parameter drift of 10% on all PMOS transistors for 10 years. It was fo...

A High Speed and Low Voltage Dynamic Comparator for ADCs

Abstract — A new dynamic comparator is proposed and it is compared with two existing comparators in terms of voltage, delay and frequency. CMOS dynamic comparator which has dual input, dual output inverter stage suitable for high speed ADCs with low voltage and low power dissipation. A conventional comparator is replaced with dynamic comparator which reduces the delay and voltage which increase...

A Coupled Inductor Based High Voltage Gain DC-DC Converter Using Interleaved Voltage Multiplier Cells

In this work, a non-isolated high step up DC-DC converter using coupled inductor and voltage multiplier cell is proposed. The proposed converter conversion ratio is efficiently extended by using a coupled inductor. An interleaved configuration of two diode-capacitor cells is applied to step up the voltage conversion ratio and decrease the voltage stress across the switches. Also, in the suggest...
