In the past, a large number of new active building blocks have been proposed and published by many researchers all over the world. In most cases, these new building blocks were used for realizing novel filter and/or oscillator circuits.
In addition to the well known amplifier types
Operational Amplifier (opamp), Current Feedback Operational Amplifier (CFOA), Operational Transconductance Amplifier (OTA),
here are some of these new active blocks:
Multiple Output OTA (MO-OTA),
Current Follower (CF),
Current Feedback Differential Difference Amplifier (CFDDA)
Current Conveyor: first, second and third generation (CCI, CCII, CCIII),
Differencing Voltage Current Conveyor (DVCC) ,
Operational Transresistance Amp (OTRA),
Differential Difference Amplifier (DDA),
Current Differencing Buffered Amplifier (CDBA),
Current Differencing Transconductance Amplifier (CDTA),
Current Follower Transconductance Amplifier (CFTA),
Current Conveyor Transconductance Amplifier (CCTA),
Current Backward Transconductance Amplifier (CBTA)
Current-Controlled Multiple Output Current Conveyor (CC-MOCC)
Differencing Voltage Transconductance Amplifier (DVTA),
Voltage Differencing Inverting Buffered Amplifier (VD-IBA).
Since I have not been actively involved in industrial research and development for several years, I have the following question:
Does one (or more) of the mentioned novel amplifier units have a certain application in industrial practice?
