Power control device for a signal with optimized input dynamics

摘要

A signal power control device comprises two amplification channels. A first amplification channel comprises a first transconductance amplifier and a second amplification channel comprises an attenuator mounted in series with a second transconductance amplifier. Gain adjustment means allow the respective gains of the first and the second amplifier to be controlled independently, according to laws, ensuring optimum output dynamics across the entire gain range of the power control device.
