AC analysis of a common-emitter amplifier circuit begins by recognizing the capacitive reactance (XC) remains very low at the signal frequency. By considering XC as equal to zero, reducing the circuit to an ac equivalent circuit requires replacing the three capacitors in the circuit with effective...

The input terminals of the op amp are the bases (BJT) or gates (FET, MOS) of these transistors. The current source biases the transistors, and ideally each leg of the circuit is balanced so that one half of the current flows through each transistor ( IQ1 = IQ2 = IREF 2 ) and the...
rectifier circuit, each of the switching units supplying the stepped-up voltage to said capacitor through said diode so that a resulting DC across said capacitor can be provided, as a DC output voltage of the switching unit, to a respective load to be connected to terminals of said capacitor...
To drive electromechanical relays, a discrete bipolar junction transistor (BJT) or metal-oxide semiconductor field-effect transistor (MOSFET) is used along with a free-wheeling diode for inductive kickback protection. TI provides a single-chip solution that simplifies the process of driving relays. ...
The basic configuration consists of a DC power source (Vin), aninductor(L), adiode(D), a switching device (SW), a smoothingcapacitor(C), and the load resistance (Load). Vout is the output voltage. The switch is typically a power electronics device such as aMOSFETorBJT transistorcontrolle...
