Flash type Analog-to-Digital Converters (ADCs) are the most desired ones for high speed and low to medium resolution applications because of low latency and high data rate. For high speed applications flash and pipeline ADCs are often used. The flash type is the faster of two but limited to lower resolution and consumes more power due to a large number of components. Conventional Flash ADC consists of: a) 2N resistor string, b) 2N – 1 comparators, and c) thermometer to binary encoder. In this research work, a 6-bit low power Flash ADC with high conversion rate in 90 nm technology has been designed. Design of circuit and simulations are carried out in Cadence tool virtuoso platform. The utilization of an inverter as a voltage comparator is the explanation behind the strategy's name – Threshold Inverter Quantization (TIQ). The inverter switching threshold voltage Vm is characterized at Vin = Vout point on the voltage transfer curve of an inverter. In the TIQ comparator, the Vm is interior to the inverter, altered by the transistor sizes. The parallel output through the comparator array is called as thermometer code. After the comparators produce a thermometer code (TC), the thermometer code to binary code (TC-to-BC) encoder generally changes over it to a binary code (BC) in two stages. The TC is changed over to a 1-out-of-n code using ‘01’ generator before coding into BC.
