A double frequency signal generator to which a synchronization signal having a duty cycle of 1% to 999% is inputted. The synchronization signal is used for triggering of a switching component at positive and negative edges to generate a triangular-wave signal. An average of voltages of the triangular-wave...http://www.google.es/patents/US7212045?utm_source=gb-gplus-sharePatente US7212045 - Double frequency signal generator
