Piezoelectric actuator connected to the digital synthetic-impedance device (DSID) represents a modern approach for vibration damping. For efficient use of DSID there are requirements for low input-to-output time delay and high output impedance of the DSID's main part - the voltage controlled current source. In this paper we present two types of these analogue front-ends. The first discussed circuit...
Electrical Impedance Tomography (EIT) measurements normally use a VCCS (Voltage Controlled Current Source) to excite the object/media to be studied. In general a multiplexer array is used for selecting the excitation and measurement electrodes which limits the maximum current excitation frequency. In particular for breast cancer diagnosis, there are indications that tumors have impedance characteristics...
