摘要： An adaptive equalizer finite impulse response (FIR) filter for high-speed communication channels with modest complexity, where the filter is iteratively updated during a training sequence by a circuit performing the update: h(t+1)= h(t)+μ[sgn{d(t)}−sgn{z(t)−Kd(t)}]sgn{ x(t)}, where h(t) is the filter vector representing the filter taps of the FIR filter, x(t) is the data vector representing present and past samples of the received data x(t), d(t) is the desired data used for training, z(t) is the output of the FIR filter, μ determines the memory or window size of the adaptation, and K is a scale factor taking into account practical limitations of the communication channel, receiver, and equalizer. Furthermore, a procedure and circuit structure is provided for calibrating the scale factor K.

摘要： A current reference with reduced sensitivity to process variations includes a variable resistor and a control transistor. The control transistor has a current from source-to-drain that is provided by a current mirror. The current mirror also provides a current to a variable resistor that is coupled gate-to-source to the control transistor. A control loop circuit measures the reference current provided by the current mirror and modifies the resistance value of the variable resistor in response. An external precision resistor is used to measure the reference current, and current variations as a result of process variations are reduced.
