Abstract: In a digital filter, data is received through an input path, and data in the filter is transported to an output through an output path. At least one delay element is disposed on the input path, and at least another delay element is disposed on the output path. The specific positions of the delay elements on the respective paths are selected to yield an optimal combination of filter parameters including the maximum computation delay, cost, and power consumption of the filter.

Abstract: A method and apparatus is provided for comparing a first input voltage to a second input voltage. In one embodiment of the invention, a first input voltage is transformed into a first current flowing through a first transistor and a second transistor. A second input voltage is transformed into a second current flowing through the first transistor while the first current continues flowing through the second transistor. A difference current is developed which represents the difference between the first current and the second current. An indicator signal is generated which indicates the larger of the first and second input voltages based on the value of the difference current.
