Abstract
The present invention relates to a low-voltage self-calibrated peak detector (). Using a two-step calibration process that compensates the offset errors introduced by the respective first, second and third comparators (), the peak detection is made accurate whatever temperature, process or mismatch spreads. Its input bandwidth can be as high as the bandwidth of an operational amplifier of unity gain. In a rail-to-rail configuration, it can be implemented into a fully differential low-voltage self-calibrated CMOS peak detector (), which can have a very high conversion gain (α) and a very high input signal dynamic ranging.
