High-Q Active Differential Bandpass Filter Reference Design for Instrumentation Qualification
1 января 2018
The TIDA-01036reference design demonstrates a high quality factor (Q factor) active differential bandpass filter. Such filters improve signal source SNR and may be used for data acquisition (DAQ) module testing. This filter may also be used to design a signal conditioning circuit in a DAQ system analog front end.
Differential input filter supports up to 100 KHz center frequency with high quality factor Designed fully differential amplifier (FDS) for low distortion and high SNR Multiple feedback topology (MFT) is used for high quality factor High performance device characterization (A/D and D/A) and validation Compact solution that replaces bulky high order passive filter
