Özet:

 

This paper proposes current-mode first-order log-domain  filters, which are systematically derived using the state-space  synthesis procedure.  First-order low-pass, high-pass, and all-pass  responses are obtained with different circuit types.  The filter  circuits have very simple structures, since they use only bipolar  junction transistors (BJTs) and a grounded capacitor.  They can be  electronically tuned by changing an external current.  The filters  have a greater bandwidth due to inherently current-mode and log-domain  operation.  PSPICE simulations are given to confirm the theoretical  analysis.
