Single-ended to differential converter with relaxed common-mode input requirements |
摘要 |
A converter for converting a single-ended input VIN to a differential output signal VOUT 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 ("R1") coupled between the single-ended input and the positive input terminal of the fully differential amplifier, a second resistor ("R2") coupled between the fixed voltage and the negative input terminal of the fully differential amplifier, a third resistor ("R3") coupled between the positive input terminal and the negative output terminal of the fully differential amplifier, and a fourth resistor ("R4") coupled between the negative input terminal and the positive output terminal, wherein the values of such resistors are governed by: <IMAGE> The same principles can be applied to differential-to-single-ended converters as well.
