This paper describes a R-tuming CMOS Programmable Gain Amplifier(PGA) for dynamic range system. The components of the system explain a PGA with wide-bandwidth and high-resolution-gain-step through the SPI controller and using a ?? -boosting cascode in PGA. The proposed PGA consist of 2 stage PGA. Total gain is sum of each PGA갽s gain. PTAT maintained constant voltage and current depending on the temperature was applied. Also each PGA consist of BJT core, differential amplifier using a common emitter structure in used source degeneration resistor and pass gate for gain control.
