Abstract
The present invention relates to a conversion circuit that converts a single-ended signal to differential signals. According to an embodiment of the present invention, crosstalk is avoided by insuring that none of the transistors in the conversion circuit are directly connected to ground. By not having a transistor directly connected to ground, ground current is avoided and crosstalk associated with ground current is eliminated.
Claims12
A system for converting a single-ended signal to differential signals, comprising:
- a first device configured to convert a current to voltage;
- a second device coupled to the first device;
- and
- a third device coupled to the first device and second device, wherein not one of the first, second, and third device is directly connected to ground and wherein the current is amplified by a gain of more than two.
A method for converting a single-ended signal to differential signals, comprising:
- converting a current to voltage;
- inputting a differential voltage to a differential pair;
- and
- amplifying the current by a gain of more than two, wherein approximately no ground current is produced.
