Abstract: A structure and associated method for reducing a static phase error in a phase-locked loop circuit. The phase-locked loop circuit comprises a voltage controlled oscillator and a phase frequency detector. The voltage controlled oscillator is adapted to provide a first clock signal comprising a first frequency. The phase frequency detector is adapted to compare the first clock signal comprising the first frequency to a reference clock signal comprising a reference frequency. The phase frequency detector comprises a programmable circuit adapted to vary a minimum pulse width of an increment pulse and a minimum pulse width of a decrement pulse. The programmable circuit is further adapted to reduce a static phase error of the phase locked-loop circuit.

Abstract: A circuit, including: a capacitor coupled between a first circuit node and a second circuit node and that leaks a leakage current from the first circuit node to the second circuit node; and a compensation circuit adapted to supply a compensatory current to compensate for the leakage current to the first circuit node.

Abstract: An integrated circuit designed to reduce on-chip noise coupling. In one embodiment, circuit (60) includes the following: a circuit transformer (62) capable of converting a noise sensitive input reference clock signal to an output signal having a voltage compatible with a predetermined sink voltage logic level; and a biased receiver network (64) having a PFET current mirror (74) coupled with a NFET current (72), the biased receiver transistor network designed to multiply the transformer signal to offset a mutual coupling loss of the transformer. In at least one alternative embodiment, the input reference clock signal originates at an off-chip clock generator circuit (42) and the output signal from receiver (64) is input to a PLL (44). In another alternative embodiment, the transformer is a monolithic integrated transformer. Another alternative embodiment of the present invention is a method of reducing on-chip noise coupling.
