Low Frequency Doubler

US Patent:
2006026, Nov 23, 2006
Filed:
May 19, 2005
Appl. No.:
11/133024
Inventors:
Matthew Wetzel - San Diego CA, US
Harry Harberts - San Marcos CA, US
Paul Rodgers - Solana Beach CA, US
International Classification:
H03B 19/00
US Classification:
327116000
Abstract:
A circuit and corresponding method for doubling the frequency of an input signal, even when the input signal is of low frequency or a square wave. The input signal is applied to a phase-shifting circuit that produces a pair of output signals that are theoretically 90 apart in phase, but may lack the desired form if the original input signal is of low frequency. The waveforms of the two output signals are enhanced in latching hysteresis buffers that produce more uniformly squared waves, with zero crossings corrected to be more exactly 90 apart and with desirably steep state transitions. The enhanced-waveform output signals are coupled to an exclusive OR (XOR) gate to produce a double-frequency output.
