INTEGRATED CIRCUIT WITH ADJUSTABLE CONDUCTANCE BY DIGITAL CONTROL SIGNAL

摘要

PROBLEM TO BE SOLVED: To provide an integrated circuit with conductance adjustable by a digital control signal. SOLUTION: The integrated circuit has at least one adjustable conductance component 6 with a digital control signal 17 to quantize an actual value with a prescribed relative accuracyΔp. The conductance component 6 consists of basic conductance components that respectively define a numerical step to decide the conductance of each basic conductance component in a way that two consecutive numerical steps in the digital control signal 17 corresponds to only a sole numerical step of the conductance component 6. In the case that any of the two numerical steps in the digital control signal 17 results in a smaller or a larger value than the actual value, a basic conductance component corresponding thereto is made enable or disable. Thus, the adjustment sum of the conductance component 6 is equal to the actual value with the same relative accuracyΔp without being vibrated between two values that have the actual value inbetween from the smaller and the larger sides.
