  1. Bandpass filter has adjustable Q
    The bandpass filter circuit shown in Figure 1 features an electronically controlled Q. Q for a bandpass filter is defined as the ratio of the 3 dB pass bandwidth to the stop bandwidth at some specified attenuation. The center frequency of the bandpass filter...

  2. High Clock-to-Center Frequency Ratio LTC1068-200 Extends Capabilities of Switched Capacitor Highpass Filter
    The circuit in Figure 1 is a 1 kHz 8th order Butterworth highpass filter built with the LTC1068-200, a switched capacitor filter (SCF) building block. In the past, commercially available switched capacitor filters have had limited use as highpass filters because of their...
