    摘要: A first system and method relates to an analog current-mode method using branch systems. In the analog current-mode implementation, multiple branches systems can be scaled according to filter coefficients and switched using known data points. Positive coefficients can add current to the summing node, while negative coefficients can remove current from the summing node. Switches can be implemented with quick charge/discharge paths in order to operate at very high data rates. A second system and method relates to a digital look-up table based high-speed implementation. In the digital implementation, outputs can be pre-calculated as an n-bit output word that drives an n-bit DAC. Each bit of the n-bit word can then described as an independent function of the known data points. Each such function can be implemented as a high-speed combinational logic block. Both systems and methods enable the implementation of pulse shaping filters for multi-gigabit per second data transmission.

    摘要: An analog to digital converter for operating at high speeds can be implemented with a micro-comparator/sampler, an encoder, and a selector. The micro-comparator includes an input from an antenna of a receiver/transceiver system; a transistor pair; reset transistor; cascaded inverters; an inverter circuit; a buffer; and a D flip flop circuit. Depending on the number of micro-comparator/samplers placed in parallel, a number of bits can be generated. For example, 15 bits from 15 different micro-comparator/samplers can be inserted into a 15 to 4 bit encoder to generate 4 bits.
