Patent number: 11822758Abstract: A sense unit for inductive sensing or capacitive sensing is described. The sense unit may include a first terminal coupled to a first node, a first electrode coupled to the first node, and a second terminal. The sense unit may include a second electrode coupled to the second terminal. In a first mode, a first signal is received at the first terminal and a second signal is output on the second terminal, where the second signal may be representative of a capacitance of the sense unit. The sense unit may include an inductive coil. The sense unit may include a first capacitor. The inductive coil and the first capacitor are coupled in parallel between the first node and ground. In a second mode, a third signal is received at the first terminal and a fourth signal is output on the second terminal.Type: GrantFiled: November 23, 2021Date of Patent: November 21, 2023Assignee: Cypress Semiconductor CorporationInventors: Markus Unseld, Cathal O'Lionaird, Paul Walsh, Oleksandr Hoshtanar

Patent number: 11175787Abstract: An apparatus for inductive sensing or capacitive sensing is described. The apparatus may include a signal generator to output on a first terminal a first signal in a first mode and a second signal in a second mode. The apparatus may include a charge measuring circuit to receive on a second terminal a third signal in the first mode and a fourth signal in the second mode. The third signal is representative of an inductance of a sense unit coupled between the first terminal and the second terminal. The fourth signal is representative of a capacitance of the sense unit.Type: GrantFiled: March 20, 2020Date of Patent: November 16, 2021Assignee: Cypress Semiconductor CorporationInventors: Cathal O'Lionaird, Markus Unseld, Paul Walsh
