Abstrakt

Comparator is the circuit that compares an analog signal with the reference signal and produces the binary output based on comparison. A Comparator is the main block in the ADC design as it directly affects the conversion rate of an ADC. Depending on the type and architecture of the comparator, the comparator can have significant impact on the performance of the target application. The speed and resolution of an ADC is directly affected by the comparator input offset voltage, the delay and input signal range. This paper presents a high-speed TIQ comparator for flash type ADC with (Wpmos/Lpmos) > 1 to achieve minimum propagation delay.  Keywords: Analog to digital converters (ADC), threshold inverters quantization (TIQ), comparators, high speed, SoC
