Abstract
A device to sense changes in current level almost instantaneously and convert those current levels, almost instantaneously, into voltage levels that may be used by a microprocessor for logical and mathematical operations. This device employs a current conveyer to receive two inputs representing current levels. Once a sufficient difference in current levels is detected by the current conveyer, the current from each input is passed to a P-sense amplifier that converts the current to an equivalent voltage level and amplifies that voltage level. Thereafter, two outputs are generated reflecting an amplified voltage of the current input.
