Abstract
A converter for converting a single-ended input V.sub.IN to a differential output signal V.sub.OUT through positive and negative output terminals is disclosed. The converter comprises a fully differential amplifier with one of its input terminals coupled to the single-ended input and its other input terminal coupled to a fixed voltage. The converter also has a first resistor ('R.sub.1 ') coupled between the single-ended input and the positive input terminal of the fully differential amplifier, a second resistor ('R.sub.2 ') coupled between the fixed voltage and the negative input terminal of the fully differential amplifier, a third resistor ('R.sub.3 ') coupled between the positive input terminal and the negative output terminal of the fully differential amplifier, and a fourth resistor ('R.sub.4 ') coupled between the negative input terminal and the positive output terminal, wherein the values of such resistors are governed by: ##EQU1## The same principles can be applied to differential-to-single-ended converters as well.
