Ultra wide band, differental Input/output , high frequency active splitter in an integrated circuit

摘要

A wideband splitter (10) includes a core amplifier (18) for receiving a single pair of differential input signals and providing first and second pairs of differential output signals. The first pair of differential output signals and the second pair of differential outputs have substantially identical characteristics. A signal gain is implemented between the received single pair of differential input signals and the first and second pair of differential output signals. Preferably the signal gain is substantially constant across the frequency bandwidth of the core amplifier. A bandwidth peaking network (14) may be coupled to the core amplifier and includes (a) a first coil and a first resistor connected in series and (b) a second coil and a second resistor connected in series. The bandwidth peaking network is configured to increase the frequency bandwidth of the core amplifier.
