WebAnalog Predistortion Power Amplifier Using IMD Sweet Spots for WCDMA Applications Yong-Sub Lee 1, Mun-Woo Lee, Sung-Woo Jung2, and Yoon-Ha Jeong1,2 1Department of Electronic and Electrical ... Slew-induced distortion (SID) can produce intermodulation distortion (IMD) when the first signal is slewing (changing voltage) at the limit of the amplifier's power bandwidth product. This induces an effective reduction in gain, partially amplitude-modulating the second signal. If SID only occurs for a portion of the signal, it is called "transient" intermodulation distortion.
