Abstract
- This paper introduces a continuous time 5th order LP Butterworth OTA-C filter with cutoff frequency of 16 MHz. The automatic tuning system is implemented based on PLL with a special VCO. The simulation results show that the accuracy of the cutoff frequency is less than 1% and, even in the worst case, less than 3%.
