# voltage controlled voltage source example

The output of the op-amp turn on and control the MOSFET until the voltage drop across the shunt resistor became .4V. 14.8 b. This type of current source can be very useful in industrial applications. Voltage-controlled voltage source where the output is V, and A V is the constant of proportionality (voltage gain), and V CD is the parameter being sensed. Circuit with Dependent Source . Current Controlled Voltage Source CCVS H Analog Figure 1. For example, when the input voltage is .4V, the op-amp will respond to have the same voltage .4V in his feedback pin. It is responding depending on the input voltage. 14.12, the gyrator used in Sec. For example: The current source at right side bottom is a voltage controlled current source. https://www.daycounter.com/Circuits/Voltage-Servo/Voltage-Servo.phtml The Ohms law is applied in this scenario. A gyrator is shown in Fig. As a footnote, the only controlled source which has not been considered in the above worked examples is the current-controlled voltage source. Current Controlled Voltage Source (CCVS) A CCVS is a voltage source where the voltage is controlled by a current elsewhere in a circuit. Based in Austin, Voltage Control designs and … The following equation is associated with a voltage-controlled voltage source: ... An example problem for the circuit shown in Figure 1 would be to find the following: A. Here, we’ve specified a gain of 100, and a controlling current of R1.nA, meaning the current into terminal nA of resistor R1: 14.11 was replaced with a pair of voltage-controlled current sources as shown in Fig. The direction of current is from node 1 to ground. The first two examples specify a DC voltage source of 5 V connected between node 1 and ground. Voltage Controlled Dependent Voltage Source; Voltage Controlled Dependent Current Source; Current Controlled Dependent Current Source; Current Controlled Dependent Voltage Source; Using PSpice to find the Thévenin Equivalent Circuit; 3rd Tutorial: Subcircuits. This circuit is a Howland voltage-controlled current source. A transresistance amplifier outputs a voltage proportional to its input current. Note that the dependent source is found in the In Sec. AC Sources AC current and voltage sources are impulse functions used for an AC analysis. Figure 1 above shows an example of a circuit with a current controlled voltage source. Voltage-Controlled Current Source Circuit. So, it is a current source but instead of having a constant current value, it is current is always two times of the voltage drop across the at top left (). The transresistance amplifier is often referred to as a transimpedance amplifier, especially by semiconductor manufacturers.. Voltage Control is a facilitation agency that helps teams work better together with custom-designed meetings and workshops, both in-person and virtual. The third and fourth examples specify a 5 mA DC current source between node 1 and ground. Open a new PSPICE project and enter this schematic. It is scaled to provide a 20mA output current with a +1V input voltage. 14.8 a. Our master facilitators offer trusted guidance and custom coaching to companies who want to transform ineffective meetings, reignite stalled projects, and cut through assumptions.
