Ring oscillator and pulse phase difference encoding circuit

摘要

The oscillator and encoding circuit contains an integer number of inverting circuits connected together to form a ring. One inverting circuit contains an inverting starting circuit which begins the inversion of an input signal in response to an externally applied control signal. A control signal input device inputs the second control input during an interval between a first time at which the first control signal is input and a second time at which a pulse edge, which is generated at the start of the first inversion, enters the second inverting start circuit.
