ABSTRACT
This Paper introduces 4 bit flash ADC design using Linear Tunable Transconductance Element based comparators for high speed and low power consumption using 180nm technology and 90nmtechnology. Thermometer to binary decoder with low power consumption, less area & short critical path is selected for the design of low power high speed. Proposed comparator provides improved PSRR (Power Supply Rejection Ratio) compared TIQ (Threshold Inverter Quantizer) comparator NAND based topology is used which improves PSRR as well as linearity.
