  • Abstract
    An automatic tuning scheme for continuous-time bandpass filters based on a frequency synthesizer and a peak detector is proposed. A gm-C second-order filter is designed to demonstrate the proposed tuning scheme. The circuit is designed in AMI 0.5μm process. The measured frequency tuning error is 0.25%, and the Q tuning error is 3% for a 200 MHz filter with desired Q of 28.6.
