Abstract
A transistor circuit which comprises a first transistor of the N-P-N type, a second transistor of the P-N-P type and a third transistor of the N-P-N type, and in which a base of the first transistor, an emitter of the second transistor and a collector of the third transistor are electrically connected with one another, while a collector of the first transistor and a base of the second transistor are electrically connected with each other, whereby the first transistor is prevented from being driven into an extremely deep saturation region.
