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: 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 duty-cycle correction circuit corrects a clock with arbitrary duty-cycle to a 50% duty-cycle clock, with its original frequency. The device acts to translate a non-50% duty-cycle clock to an accurate 50% duty-cycle clock by utilizing a divide-by-2 frequency divider and a multiply-by-2 clock doubler to achieve conversion. The duty-cycle correction circuit increases the translation back to its original frequency while using an analog negative feedback to maintain an accurate 50% duty cycle.
