Latest Patents
Wade's latest patents include an "Apparatus and method for start-up circuit without a start-up resistor." This invention features a start-up circuit that utilizes a depletion-mode PMOS transistor and an NMOS switch. The NMOS switch is strategically placed between ground and a common gate node of a PMOS current mirror. During the start-up phase, the depletion-mode transistor creates a DC path to elevate the gate of the NMOS switch, allowing it to pull the common gate of the PMOS current mirror to ground. Once the PMOS current mirror begins generating current, the NMOS switch is deactivated.
Another significant patent is the "Band-gap reference." This reference circuit comprises a band-gap core, two current sources, and an amplifier circuit that work in harmony. The band-gap core circuit is powered by a local power supply through the first current source, while the second current source diverts excess current away from the band-gap core circuit based on a control signal. This control signal is monitored by the amplifier circuit, which forms a feedback loop compensated with a capacitor that is not tied to the local power supply. This reference circuit is particularly effective in switching applications, where rapid switching transients can affect the local supply.
