A word current source for a magnetoresistive random access memory (MRAM) circuit includes an n-channel transistor including a gate, a source and a drain, where the source is coupled to a supply ground, and the drain is coupled to the MRAM circuit. A positive supply voltage is coupled to ...
High precision extended temperature applications of the circuit of Figures 19, 20 require that the range of adjustment of VOUT be restricted. When this is done, R1 may be chosen to provide optimum zener current for minimum zener T.C. Since IZ is not a function of V+, reference T.C. wil...

A fault current limiting system for direct current circuits and for pulsed power circuit. In the circuits, a current source biases a diode that is in series with the circuits' transmission line. If fault current in a circuit exceeds current from the current source biasing the diode open, the...
In a circuit arrangement for providing a current having a controllable temperature coefficient of current, a diffused resistor (334) is used to set up a reference current in a current source (40) which has a temperature coefficient dependent upon the diffused resistor. A current mirror (352, 35...
