Abstract: An N-channel MOS monolythic R.F. Modulator for use in television games or the like is provided which internally generates an R.F. carrier signal and modulates same in accordance with the composite video output signal from the T.V. interface chip. The modulator utilizes two depletion mode MOSFETs connected in a cascode configuration, the output circuits of which are connected in series with an inductor, between a voltage source and ground. The input terminal of one of the transistors receives the composite video signal. The input terminal of the second transistor is connected to a resonant frequency circuit. The resonant frequency circuit is electromagnetically coupled to the inductor such that the current flowing through the inductor impresses a current in the resonant frequency circuit to cause same to generate the R.F. carrier signal.
