HIGH DEFINITION MULTIMEDIA INTERFACE (HDMI) APPARATUS INCLUDING TERMINATION CIRCUIT |
摘要 |
A termination circuit for a HDMI transmitter includes a bias unit and a termination resistor unit connected in parallel between a positive transmission pin and a negative transmission pin. The bias unit generates a bias voltage by selecting the higher voltage among a first voltage received through the positive transmission pin and a second voltage received through the negative transmission pin. The termination resistor unit is formed on a well region biased by the bias voltage, and conditionally provides a termination resistance between the positive transmission pin and the negative transmission pin in response to a termination resistor control signal. The termination circuit conditionally provides a termination resistance without a leakage current. The termination resistance may be varied by using an n-bit control code.
