Abstract
A multimode voltage tracker circuit is provided. The multimode voltage tracker circuit is configured to generate a modulated voltage for amplifying a radio frequency (RF) signal(s), which may be modulated in a wide range of modulation bandwidth. In one non-limiting example, the multimode voltage tracker circuit can be configured to operate in a low modulation bandwidth (LMB) mode to generate an average power tracking (APT) modulated voltage for amplifying the RF signal(s) when the RF signal(s) is modulated in a lower modulation bandwidth (e.g., <50 KHz). As such, the multimode voltage tracker circuit can be adapted to support lower bandwidth communications in an Internet-of-Things (IoT) network with improved efficiency, stability, and performance.
