Abstract
The invention relates to an amplification circuit (), comprising: a VGA (), an AGC loop () for automatically controlling the gain of the VGA (), a switching circuit () for switching between an AGC mode, in which the gain of the VGA () is automatically controlled by an output signal of the AGC loop () and a manual gain control, MGC, mode, in which the gain of the VGA () can be manually controlled by an input signal, and a read/write circuit () with a contact () for connection to a peripheral system, wherein the read/write circuit () is configured, in the MGC mode, to provide the input signal from the contact () via a write-mode path () to the VGA (), and, in the AGC mode, to provide the output signal of the AGC loop () via a read-mode path () on the contact ().
