A delay device and a delay control method are provided. The delay device includes at least one current-controlled delay group and at least one switch. The at least one current-controlled delay group is coupled to a transmission wire, each of the at least one current-controlled delay group includes at least one current-controlled delayer, and each of the at least one current-controlled delayer provides a delay according to a control voltage. The at least one switch is coupled between the at least one current-controlled delay group and the transmission wire, and each of the at least one switch is turned on or off according to a bit of an enable signal applied thereto. In the disclosure, the generated delay can be dynamically adjusted and cannot be affected by parasitic capacitance.

Delay device and delay control method

A delay device and a control method of transmission delay capable of performing temperature compensation are provided. The delay device includes a first current source, a second current source, a first resistor, and a delay adjustment circuit. The first current source is configured to provide a first current with a constant temperature coefficient. The second current source is connected to the first current source in parallel and is configured to provide a second current with a negative temperature coefficient. A first terminal of the first resistor is coupled to the first current source and the second current source. A second terminal of the first resistor is coupled to a reference ground terminal. The first resistor generates a control voltage at the first terminal of the first resistor according to the first current and the second current. The delay adjustment circuit is coupled to a transmission wire. The delay adjustment circuit determines a signal transmission delay of the transmission wire according to the control voltage.
