Abstract
A CMOS buffer receiver is provided for converting TTL or CMOS input voltage signals to CMOS signals so as to drive CMOS loads on VSLI chips. The buffer receiver comprises a reference voltage generator coupled to a compensation network having an output signal which varies with process, temperature and voltage supply. The compensated output signal is coupled to the gates of any number of current source load transistors of a plurality of series connected transistor pairs which comprise individual stabilized input converters all of which have their switchpoint located in the middle of their characteristic curves so that their switchpoints are immune to process, temperature and supply voltage variations.
