A Single Power Supply 10Bit Video Bi-CMOS Sample-and-Hold IC

A new single power supply 10bit video Bi-CMOS sample-and-hold IC is described. High speed, low power and high-accuracy sample-and-hold operation has been achieved using the complementary connected buffer type sample switch. The equivalent PNP transistor is formed by the combination of NPN and PMOS transistors. The sample-and-hold IC has been implemented in 1.2um Bi-CMOS technology. The acquisition time and the switching settling time are 20ns and 15ns, respectively. It works with +5V single power supply and the power dissipation is 150mW.
