摘要： A differential gain stage includes a plurality of programmable passive circuit component arrays operable to set a gain of the gain stage. The gain stage also includes an active switch gate control circuit and a passive switch gate control circuit. The active switch gate control circuit controls a gate voltage applied to transistor switch components of each programmable passive circuit component array as a function of the level of common mode disturbance input to the differential gain stage for common mode frequencies below a particular frequency threshold. The passive switch gate control circuit controls the gate voltage applied to the transistor switch components as a function of the level of common mode disturbance for common mode frequencies above the frequency threshold. The differential gain stage can for part of a receiver such as an xDSL receiver.

摘要： Bridge circuit for echo suppression for a reception signal of a communication device connected to a transmission line, to which can be supplied a reception signal received via the transmission line and a transmission signal to be transmitted by the communication device via the transmission line. The bridge circuit is designed such that on balancing the bridge circuit, the reception signal there can be tapped echo-compensated with a transmission signal part generated by the transmission signal being suppressed. To balance the bridge circuit a variable simulation device is provided to simulate at least one circuit section of at least one bridge branch and connect with the at least one bridge branch. By such an arrangement, the signal level in the simulation device may be reduced so far that this can be designed as an integrated circuit and to be programmable.
