Electronic circuit for high resolution measuring of times using oscillator

摘要

The electronic circuit has a first unit (3) for coarse time measurement, in which the number of oscillation cycles is counted. A second unit (7) for fine measurement includes a gate chain (5), in which the phase position of the instantaneously applied cycle of the oscillation at the time of the ending of the time determination is determined. The cycle flank is determined based on the time since the occurrence of the cycle flank. A processing unit communicates with the first and second units. The gate chain (5) is connected to the separate oscillator (1). The gate chain is designed as a geometrically linear gate chain. The circuit elements (6) have a delaying function. The gate chain (5) consists of identical non-inverting circuit elements (6).
