RF emission spectrum randomization and targeted nulling for an electronic device

In an example, a processing system for an electronic device, such as a capacitive sensing device, includes a reservoir capacitor configured to store charge from a charge pump, and a control circuit configured to operate the charge pump at irregular intervals to transfer charge to the reservoir capac...
