ABSTRACT:
A high speed analog-to-digital conversion method and apparatus including a plurality of parallel analog-to-digital converters is disclosed. A clock signal is applied to each of the analog-to-digital converters at different phase relation to increase the equivalent sampling frequency by multiplexing the outputs into a serial form. A reference signal such as a linear ramp or sawtooth signal is used to maintain the correct phase relation, thereby eliminating any errors due to differences in electrical characteristics among the analog-to-digital converters. Such correction may be performed automatically by using a CPU before digitizing an analog input signal or at any desired time.
