Abstract
Various transmission systems may benefit from techniques to improve the quality of the transmission. For example, certain full duplex transmission systems may include a virtual hybrid coupler. A circuit can include a first feedback resistor. The circuit can also include a second feedback resistor coupled to the first feedback resistor. The circuit can further include a first set of M transistors coupled to the first feedback resistor. The circuit can additionally include a second set of N transistors coupled to the second feedback resistor and to the first set of M transistors. The circuit can be configured to cancel a transmitted signal at a receiver input based on a ratio of resistance values of the first feedback resistor and the second feedback resistor, and based on a ratio of M to N.
