Spiking Cochlea With System-Level Local Automatic Gain Control

Tactile sensor with automatic gain control

This paper proposes a new tactile sensor capable of automatically adjusting the sensitivity of each sensor unit, depending upon the contact information. Suppose a strain gauge based tactile sensor composed of multiple sub-sensor units and a single AD-DA port. For such a sensor system, we introduce two key components; the Analyzer, how to determine the contact force quickly from each sub-sensor ...

Automatic Gain Control (AGC) circuits

In the early years of radio circuits, fading (defined as slow variations in the amplitude of the received signals) required continuing adjustments in the receiver's gain in order to maintain a relative constant output signal. Such situation led to the design of circuits, which primary ideal function was to maintain a constant signal level at the output, regardless of the signal's variations at ...

Automatic Gain Control (AGC) in Receivers

AGC was implemented in first radios for the reason of fading propagation (defined as slow variations in the amplitude of the received signals) which required continuing adjustments in the receiver‟s gain in order to maintain a relative constant output signal. Such situation led to the design of circuits, which primary ideal function was to maintain a constant signal level at the output, regardl...

Automatic Gain Control in Wcdma Terminals

This article gives a presentation of the Automatic Gain Control algorithm used in WCDMA (3rd generation mobile networks). The focus is on how the controller bandwidth influences settling times and modulation distortion. This will be investigated through simulation for two different channel cases.
