Abstract
An analog multiplier for multiplying the signals derived from a charge coupled device (CCD) tap includes a balanced multiplier of a first conductivity-type and a buffer of a second conductivity-type coupled between the CCD tap and the balanced multiplier. The multiplier includes first and second transistors, the drains of which are coupled together to form an input. The buffer includes a load transistor coupled to the output of an amplifying transistor. Means are included for coupling the output of the amplifier transistor and the multiplier input.
