Current to Voltage Converter Circuit

Current to Voltage Converter Circuit: A device that produces a voltage proportional to input signal current is called a Current to Voltage Converter Circuit. The circuit arrangement is shown in Fig. 36.27. In this circuit, a photocell or photomultiplier tube that provides output current proportional to the light flux but independent of the load impedance, …

Frequency Response of Common Mode Gain of Differential Amplifier

Frequency Response of Common Mode Gain of Differential Amplifier

Frequency Response of Common Mode Gain of Differential Amplifier: Low values of common-mode gain are desirable so that the circuit can reject undesirable signals that are applied equally to both inputs. The common-mode (CM) gain becomes important because undesired common-mode signals may have high-frequency components. The important aspects of the Frequency Response of Common Mode …

Single Stage Amplifier Frequency Response and Phase Response Curves

Single Stage Amplifier Frequency Response and Phase Response Curves: The voltage gain of a single-stage transistor amplifier commences to fall off at some high frequency. This fall-off may be due to the construction of the individual transistor or to stray capacitance in the circuit. Gain-frequency response of single stage amplifier is depicted in Fig. 35.1, …
