A circuit comprises P-channel and N-channel field effect transistors. A conduction electrode, such as a drain, of one of the transistors is coupled to a conduction electrode of the other transistor. Means are provided for ensuring that the currents in the transistors when changing state, and hence the rise and fall times of an output signal of the transistors, are substantially equal. Preferably, the ensuring means comprises the channel length of the P-channel transistor being smaller than that of the N-channel device. Alternately, either the doping level or the width of the P-channel device can be greater than that of the N-channel device.
