摘要： System and method for providing a programmable power supply. The programmable power supply may include a programmable hardware element (PHE) that couples to a power supply (DC-DC converter) and which in turn couples to a linear regulator. The PHE may implement a PID control algorithm that receives a measurement of the output power and may use PID and/or non-linear control to ensure that the power supply and the linear regulator maintain similar power levels. The PHE may be configured based on a graphical program, thus enabling fast and efficient modifications to the programmable power supply.

摘要： The JFET transistor differential amplifier herein serves as an input stage, as for an electrometer operational amplifier, and exhibits high input impedance and low leakage current. This is achieved by biasing the JFET transistors so as to operate in the ohmic region rather than the saturation region of their characteristic drain current-gate to source voltage curve.

摘要： A current in a circuit is measured without breaking the circuit. A relatively low resistance element in the circuit such as a component lead is chosen. A current is forced through the element and the voltage drop measured. Another current is forced through the element and the voltage drop measured. The values of these currents and voltages are used to determine the original current in the circuit.
