4.25Gbps Transimpedance Amplifier with AGC
... The AGC circuitry lowers the effective transimpedance feedback resistor RF by means of a MOSFET device acting as a controlled shunt. This prevents the transimpedance amplifier from being overdriven at high input currents, which leads to improved jitter behavior within the complete input-current dyna ...

Stray voltage
Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations, due to normal current flow in the power system. Large voltages can appear on the enclosures of electrical equipment due to a fault in the electrical power system, such as a failure of insulation.
