Schematic of the voltage to current converter circuit Circuit Diagram In the test case 1, the input current across the op-amp is given as 1mA.As the input impedance of the op-amp is very high, the current start to flow through the feedback resistor and the output voltage is dependable on the feedback resistor value times the current is flowing, governed by the formula Vout = -Is x R1 as we discussed earlier.. In our circuit the value of Resistor R1 is 1k.
We can therefore construct a circuit that converts a voltage to a current. Looking at the datasheet for the LM324 we can see it's capable of driving 30mA and can therefore be used as the basis of our simple current source without an additional drive transistor. In addition to that we'd like a 0-10V or +/-10V output.

A boost converter (step-up converter) is a DC-to-DC power converter that steps up voltage (while stepping down current) from its input (supply) to its output (load). It is a class of switched-mode power supply (SMPS) containing at least two semiconductors (a diode and a transistor) and at least one energy storage element: a capacitor, inductor DC converters can also serve as switching mode regulators to convert a DC voltage, normally unregulated, to a regulated DC output voltage. Buy Now. This simple voltage booster circuit can boost the voltage of a 1.5V AA battery to 40V to 70V DC. The output current of the circuit is around 20mA. The circuit can work for any application
Learn how to make simple boost converter circuits using transistors, and IC 555. These step up circuits will convert 1.5 V 3 V to 12 V, 24 V. You can use a 9V 5 amp transformer to build the voltage/current source for the LM317 circuit. You can try the following circuit for the mentioned purpose. Use only 2nos of 2N3055 in the circuit, that

Convert Current to Voltage. It is extremely simple to measure 0-20 mA signal with a device that will measure only Voltage inputs. If the Voltage input module available will accept a 0-10 Vdc signal, but may not accept a 0-20ma signal directly.
