Variable gain amplifiers often use a mechanical potentiometer to set the gain. An example is a volume control dial. However, when the analog signal path is digitally controlled, a digital ...
AGC (automatic-gain-control) amplifiers use the nonlinear characteristics of control devices. The magnitude of the real component in some of their differential parameters changes depending on ...
Variable Gain Amplifiers (VGAs) implemented in Complementary Metal-Oxide Semiconductor (CMOS) technology have emerged as a critical component in modern analog and mixed-signal systems. These ...
In the process of creating various products that deal with analog signals, one frequently requested function is automatic gain control. This feature is needed to control the amplitude of a given input ...
