Abstract: A DC-balanced signal is imposed on the input of a transmission line. Prior to imposing the DC-balanced signal, the input of the transmission line is held at an intermediate DC level that intermediate between the maximum and minimum DC levels of the DC-balanced signal. Alternatively, a compensating pulse is additionally imposed on the input of the transmission line. The compensating pulse compensates for a change in the DC level at the output of the transmission line caused by the imposing of the DC-balanced signal on the input of the transmission line.

Abstract: A circuit and method for performing track and hold operations utilizes a circuit configuration in which a hold capacitor connected to a track signal path can be selectively isolated from an input signal applied to a control device on a common signal path by a switching mechanism, which is used to switch the circuit between track and hold modes of operation. The switching mechanism operates to connect either the track signal path or a hold signal path to the common signal path. When the track signal path is connected to the common signal path, electrical charge is allowed to be stored in the hold capacitor. When the hold signal path is connected to the common signal path, the hold capacitor is electrically isolated to hold the stored electrical charge.

Abstract: An attenuating-and-amplifying circuit and method for producing a voltage-adjusted output signal of an input signal uses a voltage divider and a number of switchable amplifier units connected to the voltage divider to adjust the gain or attenuation of the input signal. The voltage divider includes a number of tapping nodes, which are connected to the switchable amplifier units. The voltage divider is configured to provide different voltage attenuated signals of the input signal. The switchable amplifier units can be selectively activated to adjust with respect to voltage at least one of the different voltage attenuated signals to produce the voltage-adjusted output signal.

Abstract: A multi-device system and method for controlling voltage peaking of an output signal transmitted between input and output circuits of integrated circuit devices utilizes various electrical elements that can be adjusted after the fabrication of the integrated circuit devices to change the impedance of the input and output circuits. These adjustable electrical elements include one or more pass transistors in the input circuit whose on-resistances can be changed by adjusting a control signal supplied to the pass transistors. The adjustable electrical elements may also include one or more of the following: an adjustable current source, an adjustable resistor and a resistance-adjustable transistor operated as an adjustable resistor.

Abstract: A circuit and method for correcting thermal deviations of one or more output signals from an amplifier utilizes Early effect-compensated correcting signals to reduce the thermal deviations of the output signals. The correcting signals are derived from temperature-dependent signals, which correspond to the thermal deviations of the output signal. The temperature-dependent signals, however, include errors due to Early effect. The Early effect errors are compensated in the correcting signals by introducing reverse Early effect errors into the correcting signals. Consequently, the compensating signals can be used to more effectively correct the thermal deviations of the output signals.
