Abstract

Apparatus, systems, and methods are disclosed, including a high-voltage charge pump including multiple pump stages connected in series to provide a high-voltage output, a common discharge circuit, and multiple high-voltage devices coupled between the outputs of each of the multiple pump stages and the common discharge circuit. Each of the multiple pump stages include a low-voltage switching device. The common discharge circuit is coupled to each of the multiple pump stages and is configured to discharge the multiple pump stages when the multiple pump stages are disabled. The multiple high-voltage devices include a respective high-voltage device coupled between an output of each of the multiple pump stages and the common discharge circuit.
