摘要:
A transmission gate switch includes a switching unit to conduct a switching operation between first and second nodes in response to a switching signal, and an isolation unit to prevent the switching unit from being turned on by a negative swing of the first or second node while the switching unit is being turned off.

A short pulse rejection circuit may include an edge detector, a filter circuit, a comparison circuit, and a gating circuit. The edge detector may delay an input signal to generate a delayed input signal, and detect an edge of the input signal to generate an edge detection signal. The filter circuit may perform a low pass filtering on the edge detection signal to generate a first signal. The comparison circuit may compare the first signal with a reference voltage. The gating circuit may gate the delayed input signal based on an output signal of the comparison circuit. Therefore, the short pulse rejection circuit may have a sufficient setup/hold time margin of a flip-flop, and may sample an input signal even when a state of the input signal does not change during an initial operation.

A circuit for controlling impedance may include an impedance adjustment circuit and a control signal generation circuit. The impedance adjustment circuit may adjust an impedance value based on a control signal. The control signal generation circuit may provide the impedance adjustment circuit with a control signal that corresponds to one of an impedance value at a first clock cycle and an impedance value at a second clock cycle that approaches a target impedance.

A transmission circuit includes a serial clock generator, a serializer and a transmission clock generator. The serial clock generator generates a serial clock. The serializer serializes N-bit parallel data to N-bit serial data in synchronization with the serial clock. The transmission clock generator receives the serial clock to generate a transmission clock that has a same delay as the N-bit serial data, and the data transmission circuit simultaneously transmits the N-bit serial data and the serial clock.

An AD converter is provided. The AD converter includes a light source unit which provides an optical signal, at least one waveguide unit which consists of a photonic crystal and transmits the optical signal, a modulation unit which applies a RF signal to the at least one waveguide unit, thereby modulating an optical signal output from the at least one waveguide unit, and a digital conversion unit which converts the modulated optical signal to a digital signal. Accordingly, a compact-sized AD convert can be realized.
