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: {overscore (h)}(t+1)={overscore (h)}(t)+μ[sgn{d(t)}−sgn{z(t)−Kd(t)}]sgn{{overscore (x)}(t)}, where {overscore (h)}(t) is the filter vector representing the filter taps of the FIR filter, {overscore (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 novel circuit technique for reducing leakage currents through the read-path of large register files in which a negative gate-source voltage is forced on a critical pass transistor between a cell read transistor and a local bitline such that when the cell is in a first state, the leakage current from a dynamic node of the cell read transistor is reduced. The reduced leakage current increases the robustness and performance of the read operation.

摘要： A low power architecture for register files is provided. A decoder receives a specified bit address divided into a first input and a second input. The decoder is split into a first stage and a second stage. A pre-decoder in the first stage receives the first input, identifies a local bitline that is accessed, and outputs a first signal to a register file array. A post decoder in the second stage receives the second input and the first signal, processes the identification of the local bitline, and generates a second signal to be sent to the register file array. A delay synchronizes the first signal and the second signal so that both signals reach the register file array simultaneously.
