Frequency Doubler Schematic. Figure below shows the schematic diagram of the circuit and the pulses in different test points in the circuit. Like other doublers this circuit uses both the rising and falling edges of the input signals to produce digital pulses thus effectively doubling the input s frequency.
During the negative half cycle of the sinusoidal input waveform diode d1 is forward biased and conducts charging up the pump capacitor c1 to the peak value of the input voltage vp because there is no return path for capacitor c1 to discharge into it remains fully charged acting as a storage device in series with the. A frequency doubler is a non linear device that effectively produces an output signal that is twice the frequency of the input signal. Where f double is the desired doubled output frequency.
The circuit shows a half wave voltage doubler.
The frequency doubler uses only a single integrated circuit. Frequency doubler with 4011. The minimum carrier to noise degradation δcnr in decibels caused by an ideal frequency multiplier is. A few simple selections configure this circuit for an application.
