ABSTRACT:
An analog delay circuit provide a current-dependent delay through two differential pairs of transistors operated in parallel, one with input resistors, the other without. Delay is varied through the delay stage by provision of complementary currents produced by a current DAC in response to digital code provided in a data bus. The complementary currents drive the differential pairs to various combinations of operations, which yields the desired variable delay.
