of these devices are labeled d, s, and g, respectively. The gate of the JFET is directly coupled to the source of the silicon MOSFET, thereby forming a three-terminal circuit wherein the series combination of the normally off MOSFET and the normally on JFET forms a normally off circuit. ...
For example in the conventional circuit, as Q1 is turned on and Q2 turned off, a very high current flows through the MOSFET pair, since Q2’s body diode appears as a short circuit during its reverse recovery time. Other losses arise due to discharging Q1’s output capacitance, and to...
A Cross coupled MOSFET-based circuit can also provide a virtual negative resistance in the circuit. Due to the direct connection of the upper transistor gates to the input voltage, the voltage drop presented by the rectifier is greatly reduced in GCC topology. This circuit’s efficiency has ...
This combination of features allows for very small, low profile buck switching regulator circuit implementations with minimum external components. Step-Up (Boost) Regulators Analog Devices manufactures a broad line of high performance, step-up boost switching regulator ICs and boost switching ...
MOSFET responsive to a relationship between voltages present at the first and second conduction terminals, respectively, of the synchronous rectifier MOSFET so as to prevent any P-N junction in the synchronous rectifier MOSFET from becoming forward-biased; and an adaptive clamping circuit comprising a...
