  • Patent number: 5590154
    Abstract: An equalizer circuit (11) and a method for adjusting tap weights in the equalizer circuit (11) to provide an equalized signal. The equalizer circuit (11) includes an adaptation circuit (16) coupled to an FIR filter (17) and to an error sign generating circuit (18). The FIR filter (17) provides the signs of a plurality of delay signals to the tap weight adaptation circuit (16). Likewise, the error sign generating circuit (18) provides a sign of the error of an output signal of the FIR filter (17) to the tap weight adaptation circuit (16). The tap weight adaptation circuit (16) uses the signs of the delay signals and the sign of the error signal to generate the tap weights which are passed to the FIR filter (17) for adjusting the tap weights of the FIR filter (17).

  • Patent number: 5345190
    Abstract: A modular filter (11) that operates at low voltages and utilizes common mode feedback is described. The modular filter (11) receives an input differential signal and provides a filtered output differential signal. The modular filter (11) comprises a load circuit (15) , a first transconductor (18) , a second transconductor (24) , an amplifier (19), and a common mode amplifier (26). The first transconductor (18) has a transconductance gml and the second transconductor (24) has a transconductance g.sub.m2. The amplifier has a gain K. The modular filter (11) provides a transfer function of V.sub.o /V.sub.i =(g.sub.m1 /g.sub.m2)*((1+(sKC.sub.a /g.sub.m1))/(1+(s (C.sub.a +C.sub.b)/g.sub.m2)), where C.sub.a are capacitors (21 and 22) that capacitively couple outputs of the amplifier (19) to the load circuit (15) and C.sub.b are capacitors (27 and 28) that capacitively couples the output of the common mode amplifier (26) to the load circuit (15).
