The continuous reduction of power supply voltage for VLSI circuits put forward new challenges for analog designers. In this paper we present a low-voltage CMOS amplifier with rail-to-rail input common-mode range. The amplifier was designed with 1V supply voltage in standard digital technology. Alternative methods were applied for obtaining high ICMR, good CMRR and output swing at such low supply voltage. A bandgap reference was designed with same supply using current-mode technique.
