The gate charge recovery circuit comprises the combination of a capacitor connected between the reference terminal of the semiconductor device and the positive terminal of a driver and a filter resistor connected between the positive terminal of the driver and the positive terminal of a voltage source...
a switching circuit configured to selectively couple the second current to said reference node in response to a gate stress test enable signal; a first resistor coupled between the reference node and a drive node of the power transistor across which the reference voltage is generated; wherein said...
In order to charge and discharge the gate of a power device, energy must be expended. If the equivalent capacitance model is used, and full charging and discharging of the gate occurs each switching cycle, the power dissipated by the gate switching action for both isolated and nonisolated gate...
The proposed circuit exploits a pre-charge structure that alleviates the leakage current and long-term stress of a driving TFT during the touch sensing operation. Simulation results confirm that the proposed gate driver circuit can generate a highly uniform output waveform after each touch sensing ...
In this paper, the design of a XOR/XNOR gate for low-power cryptographic applications is presented. The proposed gate optimizes the SABL (Sense Amplifier Based Logic) gate, widely used in cryptocircuit implementations, by removing residual charge in the pull-down circuit and simplifying the pull...
The flat-band voltage (VFB) is defined as the applied gate voltage such that there is no band bending (or no electric field) in the semiconductor and, as a result, zero net space charge in the region. From: Comprehensive Materials Processing, 2014 ...
