Delay method, circuit and integrated circuit

摘要

This document discusses, among other things, a delay circuit, in which a first register is written with a delay reference code, a second register is written with a delay factor, a control unit determines a corresponding delay ratio in a storage unit based on the delay factor in the second register, and sends the determined delay ratio to a first digital timing unit, the first digital timing unit determines a delay reference time based on the delay reference code in the first register, multiplies the delay reference time by the delay ratio to result in a desired delay time, and generates a delay.

1. A delay circuit, comprising:
an oscillator configured to supply clock signals; a first register configured to be written with a delay reference code; a second register configured to be written with a delay factor; a storage unit configured to store delay factors and corresponding delay ratios; a control unit configured to determine a corresponding delay ratio in the storage unit based on the delay factor in the second register; and a first digital timing unit configured to receive the determined delay ratio from the control unit, to determine a delay time based on the delay reference code in the first register and the delay ratio, and to generate a delay based on the delay time.
