A 4096 cell switched capacitor analog waveform storage integrated circuit

A full-custom switched-capacitor transient analog waveform storage and reconstruction integrated circuit containing 4096 sample and hold cells has been designed, fabricated, and tested. The switched capacitor array (SCA) is organized as 16 parallel channels of 256 serially addressed samples per channel with multiplexed and buffered analog output. Signal sampling frequencies of up to 100 MHz have been accomplished, with a dynamic range, measured at 10 MHz, of at least 8000 to 1. The circuit operation and performance are described, limits on performance are examined, and future implementations are discussed
