  • Digital quadrature transmitter with class-B I/Q cell sharing
    Patent number: 10200232
    Abstract: A digital quadrature architecture is presented that employs switched current digital power amplifiers and uses a digital class-B input code profile in combination with non-overlapping LO signals to overcome the low efficiency problems of conventional quadrature architectures. By employing digital class-B signals, the number of I/Q cells is reduced to half and the need for extra processing of the sign bits is eliminated in the transmitters, thereby improving the efficiency.
