Patent attributes
A transmitter, a receiver, and a transceiver for use in a wireless communication system are disclosed. In one embodiment, the radio frequency (RF) transmitter comprises a first parallel-to-serial converter to convert first parallel data corresponding to a I quadrature baseband signal component into a first set of serial data bits, a second parallel-to-serial converter to convert second parallel data corresponding to a Q quadrature baseband signal component into a second set of serial data bits, and one or more stages having a first XOR gate coupled to a gate terminal of a first transistor and a second XOR gate coupled to a gate terminal of second transistor. The first XOR gate has a pair of inputs coupled to the first set of serial data bits and a first clock (e.g., an I clock) that corresponds to the I quadrature baseband signal component, and has a first output coupled to drive the gate terminal of the first transistor, while the second XOR gate has a pair of inputs coupled to the second set of serial data bits and a second clock (e.g., the Q clock) that corresponds to the Q quadrature baseband signal component, and has a second output coupled to drive the gate terminal of the second transistor. The first and second outputs are summed at a node to obtain a single-side band (SSB) RF output.
