Patent CA-1328126-C (CA)
Title: Signal generator utilizing a combined phase locked and frequency locked loop
Inventor: CURTIS GEORGE S
IPC: H03C3/00
Filed: 1989-09-07
Granted: 1994-03-29
Abstract: ABSTRACT           A programmable  low noise  frequency modulated signal source including a voltage controlled oscillator (VCO) having a frequency locked loop (FLL) constituting a first feedback path and a phase lock loop (PLL) constituting a second feedback path is provided.   The PLL includes a VCO, a programmable fractional-N frequency division network and a phase detector for comparing the phase of the VCO output signal with the phase of a reference signal and for producing an error signal to controllably adjust the output frequency of the VCO.   The FLL includes a delay line frequency discriminator, a loop amplifier and filter to provide a feedback signal to a frequency control terminal of the VCO.  The frequency discriminator includes a first signal path having a frequency sensitive time delay network to provide a phase shift as a function of the VCO output signal frequency and a second signal path which includes a voltage controlled phase shifting network.  The error signal derived from the PLL phase detector is coupled to an input terminal as the voltage controlled phase shifting network.  The POL error signal in combination with a bias signal adjusts the phase difference between the two frequency discriminator signal paths to set the operating point of the FLL phase detector such that the VCO output signal will have a desired frequency and minimum phase noise.

Abstract: Abstract An RF power amplifier having improved amplifier protection.  An RF source provides an RF signal to be amplified.  The amplifier includes a bridge circuit having an input circuit adapted for connection across a DC voltage source and an output circuit connected across a load.  The bridge circuit includes first and second transistors for, when on, connecting the DC voltage source across the load for DC current flow therethrough in a first direction and third and fourth transistors for, when on, connecting the DC voltage source across the load for DC current flow therethrough in a second direction.  The transistors are controlled in response to the RF signal so that they turn on and off at a frequency dependent upon that of the RF signal and in such a manner that current flows from the DC source alternately in the first and second directions through the load.  An amplifier control serves to apply a reverse bias to the second and fourth transistors to prevent them from conducting current until receipt of a turn on signal.  The turn on signal is provided for actuating the amplifier controller to remove the reverse bias from the second and fourth transistors such that the reverse bias applied to the fourth transistor is removed during a first half cycle of the RF signal when the fourth transistor is off and that the reverse bias applied to the second transistor is removed during a succeeding half cycle of the RF signal when the second transistor is off.

Abstract: Apparatus and method is provided for making a three-dimensional film forming structure for imparting a selectively apertured three-dimensional pattern to a heated plastic matorial which is either fed in film form from a supply roll or extruded as a melt directly onto the surface of said forming structure and is subjected to a fluid pressure differential while in contact with its surface. In a preferred embodiment, the film forming structure comprises a stacked laminate of initially imperforate planar sheets having continuous patterns of apertures therein and at least one initially perforate selectively apertured planar sheet located beneath the uppermost continuously apertured sheet. The laminate forming structures is preferably tubular in shape so as to facilitate continuous plastic web processing against its outermost surface. Film to be debossed and selectively apertured is brought in contacting relation with the laminate structure and subjected to a fluid pressure differential on said forming structure while at a temperature above its softening temperature. The fluid pressure causes the heated plastic film to be debossed in those areas where said initially perforate selectively apertured lamina contacts the film and debossed and apertured in those areas where said initially perforate selecticely apertured lamina does not contact the film. The debossed and selectively apertured film is thereafter cooled below its softening temperature before removal from the forming structure.
