Abstract
A transistor circuit comprises a cancellation circuit which receives, as an input signal, an output signal of a signal circuit having at least a connection wiring and which supplies to the connection wiring a cancellation current opposite in phase and substantially equal in magnitude to a signal current supplied to the connection wiring by the signal circuit, whereby a signal voltage due to the signal current and the distributed resistance of the connection wiring is prevented from being produced.
