Figure 1 A series of LM317 circuits investigated in simulation and on the test bench for suitability as a current source. The circuit’s broadband PSRR was simulated, measured in ohms, and defined as ...

In this circuit, a PNP transistor sources current. The base voltage is about 0.7 V less than the emitter voltage. So with 10.3 V on the base, the emitter has about 11 V and R1 sees about 1 V ...

Spice is a circuit simulator that you should have in your ... 5 voltage I(R1): 0.1 device_current I(V1): -0.1 device ... First, the voltage source has an AC amplitude of 10 V (used in the ...

The compliance range for operating voltage extends from a minimum of 4 V (both circuits) to a maximum that is slightly lower for the Figure 1a circuit (90 V), because of its different output device.

Magma Acquires ACAD, Introduces FineSim Pro Circuit Simulator; Full-Chip, Tri-Mode Circuit Simulator Enables Simulation of Entire Mixed-Signal SoCs at Transistor Level July 24, 2006 09:00 AM ...

A monolithic current source uses two external resistors to program its output from 0.5 mA to 200 mA with 1% initial accuracy and a low temperature coefficient.
