Abstract: A voltage supply circuit that generates a voltage on a voltage supply node. The voltage supply circuit includes an adjustable capacitor, an alternating voltage source, a charge source, and an adjusting circuit. When the alternating voltage on the second capacitor terminal transitions low, the voltage on the first capacitor terminal also becomes low, and the charge source provides charge to the first capacitor terminal of the adjustable capacitor. When the alternating voltage on the second capacitor terminal transitions high, the voltage on the first capacitor terminal also becomes high, and charge is thereby pumped from the first capacitor terminal to the voltage supply node. The adjusting circuit periodically samples the voltage on the voltage supply node, and adjusts the capacitance of the adjustable capacitor to increase or decrease that voltage.

Abstract: A current sense circuit that allows for accurate sensing of a power current that flows through a power transistor as the power transistor ages. The circuit includes the power transistor, a sense transistor and a pull-up component. The control nodes of the power transistor and the sense transistor are connected, causing the power transistor and sense transistor to be on or off simultaneously. The pull-up component is connected between the input node of the power transistor and the input node of the sense transistor. When power is provided to the pull-up component, and when each of the power transistor and sense transistor are off, the pull-up component forces a voltage present at the sense transistor input node to be approximately equal to a voltage present at the power transistor input node, causing the sense and power transistors to age together.

Accordingly, the current sense circuit does not require an independent fixed high voltage supply in order to operate.
