Building Blocks

Charge Pump: The output current is proportional to the difference in the fill coefficients between the two input ports.
Dual Modulus Prescaler: An integer clock frequency divider with two division coefficients.
Fractional Clock Divider with Accumulator: A clock frequency divider that divides the frequency of the input signal by a fractional number.
Fractional Clock Divider with DSM: A clock frequency divider based on a delta sigma modulator.
PFD: A frequency-phase detector (CFD) that compares the phase and frequency of two signals.
Ring Oscillator VCO: The ring GUN model.
Single Modulus Prescaler: An integer clock frequency divider that divides the frequency of the input signal.
