A 1GHz 50mW dual modulus divider IC using source coupled FET logic

DUAL MODULUS BIPOLAR ECL CIRCUIT ICs have been widely used in phase locked loop(PLL) synthesizer systems. Representative applications have been in the automobile telephone or in transceivers, where low power consumption is required, because of battery operation. Accordingly, commercially available Si ECL divider ICs are not satisfactory; the lowest power consumption available is 150mW2.
