摘要：A transconductance amplifier is driven by a difference voltage which is coupledthrough a first input terminal to a first voltage-to- current converter and through asecond input terminal to a second voltage- to- current converter of identical design. Anidentical third voltage-to- current converter has its input terminal connected to the tapof a resistive voltage divider which is connected between the first and second inputterminals. The output signal of the transconductance amplifier can be taken from thecurrent outputs of the first and second voltage-to- current converters. The currentoutputs have a difference current which is proportional to the value of the differencevoltage.
