摘要： Circuitry that generates an interface signal between a first and a second integrated circuit (IC). The circuitry includes a reference circuit that provides a reference signal, an interface circuit, and a circuit element. The interface circuit is implemented on the first IC, operatively couples to the reference circuit, receives the reference signal and a data input, and generates the interface signal. The circuit element is implemented on the second IC, operatively couples to the control circuit, receives the interface signal, and provides an output signal. The reference signal can be a voltage or a current signal, and can be generated in the first or second IC. The interface circuit can be implemented with a current mirror coupled to a switch array, and can be oversampled to ease the filtering requirement. The interface signal can be a differential current signal having multiple (e.g., four, eight, or more) bits of resolution. The circuit element can be, for example, a VGA, a modulator, or other circuits.

摘要： A servo system comprising an analog sigma delta modulator for generating a normalized digital error correction signal from first and second analog control signals. The sigma delta modulator comprises an analog low-pass filter, a quantizer delivering the digital error correction signal and a multiplying DA-converter in feedback arrangement between the output of the quantizer and the input of the low-pass filter for multiplying the feedback signals with the sum of the analog control signals.

摘要： A threshold device or comparator comprises an array of energy emitters, e.g. light emitting diodes (16) or diode arrangements. The bits of a binary string are supplied to respective diodes or diode arrangements, which have the property of emitting energy of a distinguishable different characteristic depending on whether the applied bit is a 0 or 1. Sensors (18, 20) sensitive to the intensities of the respective different characteristics detect the intensities and a comparator 24 provides an output indicating the relative quantities of 0's and 1's in the binary string.
