Cmos voltage divider circuits

Abstract From the Canadian patent

Abstract of the Disclosure A CMOS fractional reference source or voltage divider circuit includes a string (chain) of CMOS pairs of transistors connected with their source-drain circuits in series and with ends of the string being connected across an input power (voltage) supply. The P-channel transistors are all matched to one another in a one to one ratio, the N-channel transistors are all similarly matched to one another. Output terminals are connected at the nodes between pairs of transistors. Accurate tracking of the voltage of the power supply is achieved by connecting each gate of the chain in a manner to insure the same source-to-gate voltage on each transistor of the pair. In the …
