Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A transimpedance amplifier comprising:
a voltage controlled operational amplifier comprising:
a non-inverting input grounded in an operation of the operational amplifier;
an inverting input configured to receive a current signal to be amplified;
an output coupled to the inverting input via a coupling resistor; and
a power-down input (PWDN input) configured to be activated on receipt of at least one power-down signal (PWDN) in such a way that at least one internal power source is then deactivated;, wherein, in operation, at least a first and at least a second follow-up signal are generated from the power-down signal (PWDN) received from the power-down input (PWDN input) by means of at least one electronic component, at least one of which initiates the deactivation of at least one internal current source, the second follow-up signal being activated after the first follow-up signal has been active for a time interval.
