• abstract: A novel power reduction technique is proposed for a sample-and-hold amplifier (SHA) with two stage operational amplifier. This technique improves the bandwidth and the slew rate of the SHA can be reduced. A variable gain amplifier (VGA) used in an analog-digital interface system for mega-pixel CCD image sensors is implemented. Fabricated in 0.25-/spl mu/m CMOS process with MIM capacitors, the VGA occupies 0.49 /spl times/ 0.49 mm/sup 2/ and dissipates 18.7 mW at 18 MHz with a supply voltage of 3.1 V.
