  In order to achieve the driver function for several types of scientific CCD
detector from E2V Co Ltd, and decreasing the size of electronics of CCD
detector system, an Application-specified Integrated Circuit (ASIC) was
designed. It provides multi-channel clocks and bias voltage for CCD driver. In
the ASIC, the clock drivers are made of a clock switch circuit and high voltage
amplifier. Two 8-bit current-steering DACs are used to adjust the driver
capability and high-level voltage of clocks. The bias drivers are generated by
8-bit current-steering DACs and off-chip operation amplifiers. The Global
Foundry 180 nm BCDlite technology is selected to implement this design. The
first version of design has been finished and the tests have been done.
