    摘要: A phase detector including a first latch and a control circuit is provided. The first latch generates a first output signal and a second output signal in response to a phase difference between a first input signal and a second input signal. Each of the first and second output signals includes first phase information and second phase information of the phase difference. The control circuit generates a phase indicating signal in response to the first phase information of the phase difference. The phase indicating signal indicates a relative position between the first input signal and the second input signal.

    摘要: Various circuit techniques for implementing ultra high speed circuits use current-controlled CMOS (C3MOS) logic fabricated in conventional CMOS process technology. An entire family of logic elements including inverter/buffers, level shifters, NAND, NOR, XOR gates, latches, flip-flops and the like are implemented using C3MOS techniques. Optimum balance between power consumption and speed for each circuit application is achieve by combining high speed C3MOS logic with low power conventional CMOS logic. The combined C3MOS/CMOS logic allows greater integration of circuits such as high speed transceivers used in fiber optic communication systems.

    摘要: An oscillation signal generator for compensating for an in-phase (I)/quadrature-phase (Q) mismatch and a communication system including the same are provided. The oscillation signal generator includes a first latch configured to generate an I oscillation signal, a second latch that is cross-coupled with the first latch and generates a Q oscillation signal, and a phase compensator connected to at least one of the first latch or the second latch. The phase compensator complementarily adjusts bias currents of the first and second I differential transistor pairs of the first latch and/or complementarily adjusts bias currents of the first and second Q differential transistor pairs of the second latch. Accordingly, the I/Q mismatch is compensated for without an additional device, so that the phase match between an I signal and a Q signal is improved in the communication system.

    摘要: A D flip-flop with a reduced power product or reduced clock line capacitance is disclosed. The flip-flop includes a half-static slave stage or a master stage with clock gating by the input and output. The half-static slave stage an output inverter and a feedback element consisting of a single switching transistor having a gate connected to the output of the flip-flop and the input of the inverter as its load. The clock gating circuit, which may comprise an XNOR gate, reduces the frequency of switching events by permitting clock pulses to pass into the master or slave stage only when the input and output of the flip-flop are at the same logical state.
