Abstract :
This paper describes two linearity enhancement algorithms for I-Q signal generation using a multi-bit complex band-pass (BP) ΔΣ DA modulator targeted for communication IC design and testing applications. The first one is a complex multi-band-pass data-weighted-averaging algorithm and the second is a self-calibration algorithm. The generated I, Q signals can be up-converted to a high frequency signal. We present their principles and MATLAB simulation results.
