Variable capacitor bank with switched capacitors and driver circuit
The granted patent (Publication Number: US11990884B2) discloses a variable capacitor bank comprising a conductive housing, an electrical bus with a first portion inside the housing and a second portion extending through it to form a port, and a switched capacitor connected to the first portion of the electrical bus. The switched capacitor includes a switch coupled to a driver circuit, with the driver circuit located outside the housing and connected to the switched capacitor through a conductor passing through the housing.
Furthermore, the variable capacitor bank includes multiple capacitor modules within the conductive housing, with the first module containing the switched capacitor. These modules are arranged asymmetrically or in a circular array around the port, with each module connected to the electrical bus through equal-length conductive paths. Additionally, the patent describes the use of multiple switched capacitors, diodes, and buses within the capacitor bank to enhance its functionality and efficiency, providing a versatile solution for various applications requiring variable capacitance.
