Patent abstract
Current conveyor based instrumentation amplifiers are disclosed. Such instrumentation amplifiers may have the higher common mode rejection ratios (CMRR), lower area requirements in integrated circuits, fewer resistors, fewer resistor matching requirements, less noise, and less distortion than prior art instrumentation amplifiers. One embodiment, with two input voltage lines and one output voltage line, comprises a single current conveyor and two resistors. Another embodiment, with two input voltage lines and two output voltage lines, comprises two current conveyors and four resistors, possibly in two matched pairs. Buffers may be used for impedance, frequency, and phase delay adjustment on any or all of the voltage lines.
