Abstract: A squelch circuit for operating at high speed and at high frequencies includes a squelch input unit, a low swing pre-amplifier and a sampling and decision circuit. The squelch input unit pre-processes the positive and negative signals of an input signal to generate four pre-processed signals that are paired and sent to the low swing pre-amplifier. The outputs of the low-swing pre-amplifier are then over-sampled by the sampling and decision circuit. Multi-phase clocks are used to control the over-sampling in the sampling and decision circuit. A logic circuit then determines if the state of the input signal based on multiple samples.

Abstract: A digital frequency comparator includes two double-edge triggered flip-flops and a combination logic. Each of the double-edge triggered flip-flops includes two D-type flip-flops and two multiplexers. The first D-type flip-flop receives a first reference clock pulse and is triggered by a data signal. The second D-type flip-flop receives the first reference clock pulse and is triggered by the reverse of the data signal. The first multiplexer provides the output of the first D-type flip-flop when the data signal is 1 and the output of the second D-type flip-flop when the data signal is 0. The second multiplexer provides the output of the first D-type flip-flop when the data signal is 0 and the output of the second D-type flip-flop when the data signal is 1. The combination logic enables an UP pulse when the data signal transmission clock is faster in frequency than the first reference clock signal.

Abstract: The present invention discloses a current feedback operational amplifier, whose input ends are connected to a first amplifier which transmits an output to the gate terminals of at least one input pair of current switches, and the source terminal of one transistor of the input pair of current switches is connected to one of the input ends. Therefore, a negative feedback loop will be established by the first amplifier and the input pair of current switches. By means of the negative feedback loop, the input impedance, offset voltage and gain error are all reduced. The input impedance of the present invention is reduced as 1/1+A times as the original one. Therefore, the aspect ratio of the transistors of the input pair of current switches is reduced.

Secondly, the second double-edge triggered D flip-flop receives a data signal and a second reference clock signal, then makes use of the positive-and-negative triggering to output a first state signal and a second state signal of the second reference clock signal. The phase angle of the second reference clock signal is 90-degree lagging behind the phase angle of the first reference clock signal.
