摘要

A second-order bandpass filter employing the operational transconductance amplifier-capacitor (OTA-C) method and featuring independent tuning of center frequency and Q is described. The filter, which is realized in 0.5-/spl mu/m GaAs MESFET technology, is intended for use in high-precision, continuous-time (CT) IF bandpass filtering applications requiring both accurate amplitude and group delay responses. The filter center frequency is tunable in the range 12-50 MHz, Q is tunable in the range 4-60, and a transfer function accuracy of the order of 1% is achieved throughout the tuning range. Active area is 1 mm/sup 2/ and static power consumption is 230 mW.
