Exam 2: Solidstate Devices in Industrial Applications, Operational Amplifiers and Linear ICS

A diode could be judged as properly functioning if it

When the pinch off voltage is applied to the gate of a JFET, the depletion region becomes large enough that conduction of current through the device stops.

An op amp in the non -inverting configuration has its negative input terminal at a virtual ground.

The pinch off voltage of a JFET is analogous to the cutoff voltage of a BJT.

Thyristors include all solid state devices that exhibit on -off behavior as opposed to allowing a gradual change in conduction.

Both the BJT and the FET are three terminal devices where the current flows through two terminals and is controlled by the third.

‪ -In designing this four -resistor bias circuit, the AC gain is set by the ratio of

Match the components with their function -R1 and C1

The gain of the non -inverting CDA and the inverting CDA is the same except for sign.

Match the input impedance with the device type -Millions of Megohms

For a high gain application, selecting an instrumentation amplifier with s low noise parameter is a key design consideration.

A voltage reference diode is a

When choosing transistors to design a darlington configuration for a gain of 1000, the sum of the gains of transistors must be greater than or equal to 1000.

The closed loop gain of an inverting and non -inverting of an op amp are equal when the external input resistor and the feedback resistor are equal.

Linear power supplies have become more popular than switching power supplies because they are more efficient.

In a summing amplifier, two or more resistors are connected to the positive input terminal of the inverting amplifier.

Filter design information that is typically not available on a bode plot is

The term "load" as applied to power supplies is defined as any device that draws current.

The ratio of the resistors in the feedback circuit in an active filter determine the filter type.
