Describes a new voltage-to-current converter. This converter combines accuracy with differential signal handling and a high common-mode rejection ratio (CMRR). An application in an instrumentation amplifier consisting of two voltage-to-current converters in a balancing circuit shows the versatility of these units in analog circuit design. A remarkable point of the instrumentation amplifier is that the bandwidth (800 kHz) remains constant although the voltage gain varies from 1 to 10/SUP 4/.
