摘要
In RF transmitter (TX) IC having an offset-QPSK modulation scheme, a sine wave of the transmission signal represented by a 12-bit digital code generated through the genetic algorithm reduces the I/Q imbalance and the intermodulation distortion in the analog circuit of the TX. It was experimentally confirmed by using test ICs fabricated in a 130-nm CMOS process.
