A2a R A26 Figure Q3a Figure Q3a shows the circuit schematic of part of an instrumentation amplifier. Show that the differential and common mode gains of the circuit are given by: (a) Aydiff 2.Ra+Rb %3D and ACM = 1 %3D Rb Including the circuit fragment shown in Figure Q3a, draw the diagram of a traditional three-opamp instrumentation amplifier. Write down expressions for the differential and common-mode gains of the complete circuit. (b) Figure Q3b shows part of a schematic for controlling a cooling fan for a high power transmitter amplifier. The fan is driven from a 0-12V variable voltage power supply and the current through the fan is monitored. This monitoring is important because if the fan stalls or is prevented from turning, excess current will flow and damage both the fan and the Fan Power Unit. The current flowing through the fan is monitored using series resistor RCM and the Instrumentation amplifier, Al. The voltage at 'Vout' is proportional to the fan current and is used by a control circuit to monitor for excessive current.

Dielectric Breakdown

A dielectric is a material with low electrical conductivity and so is classified as an insulator. Dielectric materials are used to block the flow of electricity through them, allowing them to behave as an insulators. They can also be used to store electric charge or improve capacitance.Dielectrics have no free electrons for conduction because electrons are tightly bound to the nucleus. Because dielectrics contain a small number of electrons for electrical conductivity, they have a dipole. The two primary roles of dielectrics in electrical devices are insulation and electrical energy storage. An electric field polarizes the dielectric, and the polarization of the molecules allows dielectric materials to store charge.
