    • In a first and second logic circuit controlling a driver circuit of CMOS configuration having a plurality of output transistors connected in parallel, a delay fluctuation clock signal and a delay fluctuation data signal are generated by generating multi-phase data signals from multi-phase clock signals that each have a different phase difference with respect to a reference clock signal, and using a delay circuit having a variable delay time reflecting the change of the current driving capability of the output transistors in the driver circuit. Then, changes in the current driving capability of the output transistors are detected from a phase relation between the multi-phase data signals and the delay fluctuation data signal, and if it is detected that the current driving capability has decreased, then the number of output transistors that become conducting is increased, whereas if it is detected that the current driving capability has increased, then their number is decreased.

    • A system and method of implementing precision time delays that provides important and novel improvements over prior techniques of implementing time delays by utilizing a new strategy for selecting the values in the sine and cosine lookup tables. Sine and cosine values which result in non-uniform amplitudes enable increased overall accuracy with fewer bits communicated from the look-up tables to the analogue portion of the system. Further, herein is provided the addition of a variable amplitude threshold crossing capability following the combining of the sine and cosine signals. The time delay accuracy of the resulting phase and amplitude hybrid system can be improved either by increasing the number of bits in the sine/cosine phase management section or by increasing the number of bits in the amplitude section. There is provided herein an optimum strategy for choosing the number of bits used in the phase and amplitude sections for the best overall delay accuracy with the fewest overall control bits.
