WebMay 23, 2024 · Ah, yeah, the thing about translinear circuits is, that they need really well matched transistors or they all drift like hell and have huge offsets. Even with good matching of Ube and dUbe/dT they tend to still drift a lot and be inaccurate in general. To me it the TLP always seemed at home in integrated circuits, not really in discrete designs... WebFigure 1a. The basic BJT implementation of a DC log amp has current-sinking inputs that generate negative output voltages. Figure 1b. By changing the BJT from npn to pnp, the log amp becomes a current-sourcing circuit and the output is positive. With the addition of an input series resistor, the DC log amp can also function as a voltage-input ...

WebCircuits and Systems Faculty of Engineering Imperial College London WebMar 3, 2024 · Characteristics of BJT. BJT can be connected in three different configurations by keeping one terminal common and using the other two terminals for the input and output. These three types of configurations respond differently to the input signal applied to the circuit because of the static characteristics of the BJT.
