Patent ID: 6853214

Claim:
A circuit configuration for controlling load-dependent driver strengths, comprising: an input terminal for feeding in an input signal; an output terminal for tapping off an amplified signal; a first amplifier stage having an input connected to said input terminal for feeding in the input signal and, an output connected to said output terminal for outputting the amplified signal; a reference circuit receiving the input signal, the amplified signal and a reference voltage, and performing a phase comparison between the input signal and the amplified signal, said reference circuit containing: a differential amplifier with at least two input terminals receiving the amplified signal and the reference voltage, and outputting a differential output signal; a logic combination element having a first input receiving the input signal, a second input receiving the differential output signal of said differential amplifier, and an output; and a flip-flop having an input connected to said output of said logic combination element and an output outputting a reference output signal; and a second amplifier stage connected to said output of said flip-flop and having inputs receiving the reference output signal from said reference circuit and the input signal, said second amplifier stage further having an output connected in parallel with said output of said first amplifier stage, and said second amplifier stage switching on in a manner dependent on the reference output signal generated by said reference circuit.
