DB-LINEAR VARIABLE GAIN AMPLIFIER (VGA)STAGE WITH A HIGH BROAD BAND |
摘要 |
This invention relates to a VGA stage with a novel circuit design which amplifies or attenuates a differential input signal which is transmitted by a transmission line (H). The VGA-stage comprises a operational amplifier (OPV1, OPV2) mounted in the form of a shunt feedback in order to amplify the signal; a resistance string to attenuate the signal;(RO1,RO1') and a control system (2) to switch the resistance string (RO1, RO1'). |
