In the circuit shown in Fig. 6.101c, only one active element of load capacitance
charge is present (transistor VT2), while the AT output here is formed by its emitter.
Such circuits are referred to as open emitters. In the disabled state, the circuit is
characterized by the output voltage with the value similar to
