BQTAP - Switched capacitor blocks


Question: What is the functionality of BQTAP in switched capacitor blocks (C and D types)?

Response: BQTAP is a signal that is routed from the output of the C cap (in D type SC blocks) to the input of C type SC blocks. This is a direct connection and cannot be modified. BQTAP is used in filter design and is implemented in all of the horizontal filter user modules in PSoC Designer.
