Which type of Filters?
I have known three type of filters. There are :
1) Digital Filters -A digital filter is a calculating process which is performed by digital components like DSPs or FPGAs.
2)RC-filter- They consist of RC-networks and amplifiers. The RC-filter is the Classical active filter’ (analog, continous-time).
3)SC-filter (Switched-Capacitor-Filter)- They sample signals by switching MOSFET’s. The signal conditioning however, occures in an analog way, although in principle the filter is discrete in time.
Question: From all the type of active filters which is the one that is most suitable for a band pass filter Front end transmitter for RFID application at 868 MHz using 0.5 micron CMOS technology?
ANd WHY ?
