Integrated "Low Voltage" Circuits for Economic Color Decoder Concepts

Color television is a useful area for application of integrated circuits. In particular, the demodulator section offers the possibility of using several integrated circuits provided the economy of each IC is assured by a sufficient replacement value in terms of discrete components it replaces. Under technological constraints of crystal size and power dissipation, the choice of a low voltage supply and low signal levels have the advantage of a higher replacement value then the high-voltage approach. Finally a proposal is made to integrate all the color processing IC´s into one IC, encapsulated into a 16 lead package.
