Abstract: A voltage mode signal transceiving device and a voltage mode signal transmitter thereof are provided. The voltage mode signal transmitter includes a driver, an output resistor, and a compensation capacitor. The driver provides a transmitting signal to an output end, where the output end is coupled to a receiver. The output resistor is connected in series to a coupling path between the driver and the receiver. The compensation capacitor and the output resistor are coupled in parallel. A capacitance value of the compensation capacitor is essentially equal to a capacitance value of an equivalent capacitor on an input end of the receiver.

Abstract: A multi-channel transmission device is provided. The multi-channel transmission device includes a clock generator and a plurality of transmitters. The clock generator generates input clocks. The transmitters operate based on spread spectrum clocks respectively. Each of the transmitters comprises a phase rotator. The phase rotator provides a selection signal and an interpolation signal of multiple bits. The phase rotator selects two of the input clocks as a first selected input clock and a second selected input clock according to the selection signal, and generate a spread spectrum clock according to the interpolation signal, the first selected input clock and the second selected input clock.

Abstract: A driver device includes a T-coil circuit and driver circuitries. The driver circuitries are averagely configured as a first driver set and a second driver set. The driver circuitries of the first driver set amplify one of a first data signal and a second data signal according to first portion of bits of an equalization signal, to generate a first output signal and to transmit the same to a first node of the T-coil circuit. The driver circuitries of the second driver set amplify one of the first data signal and the second data signal according to second portion of bits of the equalization signal, to generate a second output signal and to transmit the same to a second node of the T-coil circuit. The T-coil circuit further combines the first and second output signals as a third data signal, and transmits the third data signal to a channel.

Abstract: According to one embodiment, a phase interpolator comprising an alternating current (AC) coupling capacitor, and a common mode bias keeper circuit coupled to the AC coupling capacitor is presented. In one embodiment, the AC coupling capacitor may be located between a mixer circuit and an amplifier within the phase interpolator, along with the common mode bias keeper circuit coupled to the AC coupling capacitor. Alternately, in another embodiment, a second AC coupling capacitor may be located between a pre-conditioner circuit and the mixer circuit of the phase interpolator, with a second common mode bias keeper circuit coupled to the second AC coupling capacitor. In another embodiment, the AC coupling capacitor could be located only between the pre-conditioner circuit and the mixer circuit, along with the common mode bias keeper coupled to the AC coupling capacitor.
