Based on time-domain quality factor (Q-factor) measurement principle, we have proposed several architectures allowing on chip Q-factor monitoring. In our latest architecture, not only the major error sources are removed but also the remaining error source, the offset of OTA, is cancelled automatically thanks to an original joint implementation of both peak detector and comparator by a reconfigurable...
In this paper, a CMOS peak detector is proposed. The proposed peak detection is based on signal's slope variation and it can be easily exploited for positive as well as negative peak detection. Besides it can also be used for multiple peak detection without needing resetting operation, making the circuit implementation quite simple. A switched-capacitor-based (SC-based) implementation is given along...
