Precision delay circuit |
摘要 |
A precision delay circuit in an integrated circuit chip includes a transistor switching circuit in combination with a control circuit and a compensation circuit. The transistor switching circuit receives an input signal; and in response, the transistors switch on and off at an unpredictable speed to generate an output signal with a delay that has a large tolerance. The control circuit estimates the unpredictable speed at which the transistors switch and it generates control signals that identify the estimated speed. The compensation circuit includes a plurality of compensation components for the transistor switching circuit. This compensation circuit receives the control signals from the control circuit; and in response, it selectively couples the compensation components to the transistor switching circuit such that the combination of the transistors and the selectively coupled components generates the output signal with a precise delay that has an insignificant tolerance.
