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.

A spread spectrum clock generator (SSCG) and method of generating a spread spectrum clock (SSC) signal, in which the SSCG may include a controller outputting a given modulation voltage signal based on a difference between an average frequency of a first feedback signal and a comparison frequency signal input thereto, or based on comparison in total phase variations between a second feedback signal and the comparison frequency signal, and a sub-system for generating a first control voltage as a function of an input reference frequency signal and a second feedback signal input thereto. An adder may add the first control voltage signal and the modulation voltage signal to generate a second control voltage signal, and a voltage control oscillator (VCO) may generate the SSC signal based on the second control voltage signal.

A low-power multi-level pulse amplitude modulation (PAM) driver, and a semiconductor device having the same, in which the multi (M)-level PAM driver includes a load unit, first and second current sources, a pair of first input transistors, a pair of second input transistors, and a current source controller, where M is an integer greater than 3. The load unit is electrically connected to an output terminal, and the first and second current sources respectively supply a first amount of current and a second amount of current to the load unit. The pair of first input transistors electrically connects the first current source and the load unit in response to a first bit signal, and the pair of the second input transistors electrically connects the second current source and the load unit in response to a second bit signal. The current source controller activates or deactivates one of the first and second current sources in response to the first and second bit signals. Accordingly, current sources for a multi-level PAM driver are selectively activated or deactivated, thereby minimizing power consumption in the multi-level PAM driver.

In the method of controlling a slew rate, a transmission line driver may set a logic level of at least one control signal. The setting of the logic level of the at least one control signal determines a resistance on at least one path within the transmission line driver. The resistance may be adjusted so as to vary a slope of at least one driving voltage and achieve a desired slew rate.
