The proposed design employs a distinctive switching arrangement that converts non-linear errors into a constant offset and provides an initialization sub-phase before tracking. The circuit utilizes two capacitors in the signal path to enable gain flexibility, providing an accurate output during hold mode. The THA was implemented in 65-nm CMOS technology with a 1.2 V supply voltage. The results of the simulation after layout demonstrate a droop rate of 2.5mV/μS, a hold-mode settling time of 2ns for a 1pF hold capacitor.}, language = {en} }
