So sometimes it is essential to create current which is corresponding or proportional to a definite voltage. Switched mode DC-DC converter converts the DC voltage level by storing the input energy temporarily and then releases that energy at different voltage output. Consider resistance of the offset voltage compensating network to be 10Ω. This is because DC current signals will be constant throughout the circuit in series from the source to the load. Conversion from one DC voltage to another requires electronic circuitry (electromechanical equipment was required before the development of semiconductor electronics), like a DC-DC converter.

Many of these circuit designs use op-amps. Figure 4.1.1 shows a classic voltage to current (V-to-I) converter.The resistor values can be selected such that the output current in the load, varies only with the input voltage, V IN, and is independent of the load.The circuit is widely used in industrial instruments for supplying a 4 to 20 mA signal for example. The photodiode is operated in reverse bias condition. We are not going into the details here, just we will discuss the circuit given below. Shunt regulators are simple, but the requirements that the ballast resistor, R S, be small enough to avoid excessive voltage drop during worst-case operation (low input voltage concurrent with high load current) tends to leave a lot of current flowing in the diode much of the time, making for a fairly inefficient regulator with high quiescent power dissipation, only suitable for smaller loads. The output voltage is always greater than the input voltage. Perhaps the most common application of the current-to-voltage converter, also known as a transimpedance amplifier, is photodiode circuits such as the one shown below.
