Abstract
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.
