Crynodeb: | The 'APC3' is a charge sampling and storage chip designed for high speed readout of silicon detectors. It has 32 channels, each with pre-amplifier, integrator and storage capacitors. Current from a silicon detector connected to the input is integrated as a charge and stored on a capacitor. There are 128 capacitors per channel which are used sequentially to store the charge. The charge is held on the storage capacitor until it is either read-out or discarded. Logic on the chip manages the storage and retrieval of samples. This logic uses a novel architecture based on a system of pointers and read-out addresses. This paper describes the operation of the chip and measurement of its performance. |
