Abstract :
An adaptive system is described that tracks the peak of the spectral density function of the input signal. The system has been designed so that it can be easily realized in a single MOS integrated circuit using switched-capacitor (SC) techniques. Many characteristics, such as the transient response and the tracking of sine waves corrupted by noise, of a prototype (built from discrete components) are described.
