Japan, July 14 -- CYPRESS SEMICONDUCTOR CORP has got intellectual property rights for 'INDUCTIVE SENSING METHOD, DEVICE, AND SYSTEM.' Other related details are as follows:
Application Number: JP,2021-204161
Category (FI): G01R27/26@L,H03K17/95@G
Stage: PROBLEM TO BE SOLVED: To provide a method for converting a sensing inductance with an integrated circuit device into a digital value.SOLUTION: A method can include the steps of: in a first phase of a sensing operation, controlling at least a first switch SW1 to energize a sensor inductance Ls; and in a second phase of the sensing operation following the first phase, controlling at least a second switch SW2 to couple the sensor inductance to a first modulator capacitance to induce a first flyback current from the sensor inductance, the first flyback current generating a first modulator voltage at the first modulator capacitance, and according to the first modulator voltage, controlling at least a third switch to generate a balancing current flowing in an opposite direction to the flyback current at a first modulator node.SELECTED DRAWING: Figure 3 (Grant)
