Abstract: The present disclosure generally relates to biasing an isolation region in a semiconductor substrate. In an example, an integrated circuit includes a semiconductor substrate, a first rectifying device, and a second rectifying device. The semiconductor substrate has a first region, a second region, and a third region each being an opposite conductivity type from the semiconductor substrate. The first region and the second region are respective current terminals of a transistor. The first rectifying device has a first positive terminal and a first negative terminal. The first positive terminal is coupled to the first region, and the first negative terminal is coupled to the third region. The second rectifying device has a second positive terminal and a second negative terminal. The second positive terminal is coupled to a ground terminal, and the second negative terminal is coupled to the third region.
