摘要： An analog debugging block of an integrated circuit includes a multiplexor, a buffer, and a voltage-controlled oscillator. An analog voltage signal-of-interest is selectively passed through the multiplexor to the buffer. The buffer outputs an analog control voltage dependent on the selected analog voltage signal-of-interest. The analog control voltage serves as an input to the voltage-controlled oscillator and is used to control a frequency of a digital output signal generated from the voltage-controlled oscillator. The digital output signal from the voltage-controlled oscillator is driven off-chip, whereupon a frequency of the digital output signal is determined and compared against a collection of known frequencies that correspond to particular known voltages of the analog voltage signal-of-interest, thereby resulting in a determination of the value of the selected analog voltage signal-of-interest.

摘要： A method and apparatus for post-fabrication calibration and adjustment of a phase locked loop leakage current is provided. The calibration and adjustment system includes an adjustment circuit that adjusts a leakage current offset circuit to compensate for the leakage current of a capacitor. The capacitor connects to a control voltage of the phase locked loop. Such control of the leakage current in the phase locked loop allows a designer to achieve a desired phase locked loop operating characteristic after the phase locked loop has been fabricated. A representative value of the amount of compensation desired in the leakage current may be stored and subsequently read to adjust the phase locked loop.
