摘要： A switched capacitor, integrated circuit employing at least one non-linear capacitor charged and discharged in response to a reference frequency includes a first conductive device for charging the non-linear capacitor to the supply voltage in response to one polarity of the reference frequency, and a second conductive device for discharging the non-linear capacitor in response to the opposite polarity of the reference frequency to a voltage level opposite that of the voltage source minus the threshold voltage of a third conductive device in the discharge path. Preferably, a pair of non-linear capacitors are employed, each being charged on alternate half cycles of the reference frequency, and the non-linear capacitors are accumulator capacitors. The circuit also include means for rapidly initiating the charging and discharging of said capacitors and for precluding changes in the state of charge or discharge thereof due to parasitic diodes in the circuit.

摘要： Calibration systems and techniques for analog phase-lock loops (PLLs) providing the capability to dynamically maintain a constant damping factor. Damping factor is calibrated by automatically setting a reference bias current I.sub.r to the PLL's charge pump such that the charge current I.sub.c output therefrom maintains the desired PLL damping characteristic. The technique presented involves selecting a known first frequency F.sub.1 and allowing the PLL circuit to reach steady state, after which a known second frequency F.sub.2 is applied and the PLL circuit is monitored to determine whether steady state at this second frequency F.sub.2 is accomplished within a predetermined target time T.sub.x, which corresponds to the desired damping factor. The determination of whether lock occurs within the target time T.sub.x is then employed to automatically setting the reference current I.sub.r.

摘要： An optical-writing control device calculates correction values for use in correcting a transfer position at which developing-agent images are to be transferred onto a sheet, and overlaying positions at which the developing-agent images are to be overlaid, based on a detection signal output from a sensor upon detection of a correction pattern for use in correcting the transfer position and a correction pattern for use in correcting the overlaying positions. A timing of detecting the pattern for use in correcting the overlaying positions is determined based on a correction value calculated based on the detection signal output upon detection of the pattern for use in correcting the transfer position. The pattern for use in correcting the transfer position is caused to have a width, in the main-scanning direction, that is wider than the width in the main-scanning direction of the pattern for use in correcting the overlaying positions.
