  • Clock signal generator
    Patent number: 7375566
    Abstract: A clock signal generator includes a quartz crystal multivibrator circuit and a pulse-shaping circuit. The pulse-shaping circuit includes a D trigger. The D trigger includes a Q terminal, a Q? terminal, a CP terminal, and a D terminal. An output signal from the quartz crystal multivibrator is transferred to the CP terminal. The Q? terminal is connected to the D terminal. The Q terminal is an output end of the clock signal. A capacitor C4 is connected between the CP terminal and ground. A capacitor C5 is connected between the D terminal and ground. The capacitance of the capacitors C4 and C5 is adjusted to attain a clock signal of a predetermined frequency.

  • Frequency double circuit
    Publication number: 20060220712
    Abstract: A frequency double circuit includes an input terminal, a first voltage source, a multiplier, a second voltage source, and an output terminal. The input terminal receives an input signal and outputs to the first voltage source. The first voltage source filters out a direct current signal of the input signal. The multiplier includes two input ends receiving the input signal from the first voltage source for linear multiplication and gets a double frequency signal. The double frequency signal is output to the second voltage source for filtering out a direct current signal of the double frequency signal. The output terminal outputs the double frequency signal from the second voltage source.
