Space Charge Limited Circuit Building Block

The circuit shown in Fig. 1 may be employed as a building block in space- charge limited (SCL) transistor technology.

Fig. 2 shows a two input OR circuit employing the building block of Fig. 1. The output D may be connected to a building block (Fig. 1) or to a NPN-PNP inverter circuit.

Referring to the truth table, it will be seen that when either or both inputs A and B are UP, node C will be DOWN and terminal D will be UP.
