The current differencing buffered amplifier (CDBA) is a derivative of the current feedback operational amplifier (CFOA), originally proposed by Acar C and Ozoguz S. The main advantage of a CDBA is ...

Current differencing transconductance amplifiers (CDTAs) provide a versatile platform for signal processing in contemporary integrated circuits. By converting differential input currents into ...

LTspice simulation of the K2-W Vacuum Tube Op Amp’s design reveals the mad science that created a commercial revolution in 1950s and 1960s analog computing. The K2-W's first-stage differencing ...

In some applications, a linear amplifier is required which has different gains with regard to the polarity of the input signal. Figure 1 shows an inverting amplifier which is linear within the second ...

The state space model used by the STATESPACE procedure assumes that the time series are stationary. Hence, the data should be checked for stationarity. One way to check for stationarity is to plot the ...
