An 8b 350MHz flash ADC

A circuit technology and a self-aligned emitter process with poly-Si base contact, affording 350MHz conversion with power consumption of 1.5W, will be reported. A flash A/D conversion technique with error and nonlinearity suppression provides a 41.5dB SNR for a 30MHz input signal. The chip measures 3.16×82mm, with 14,000 components.
