Dl. Knee et Ce. Moore, GENERAL-PURPOSE 3V CMOS OPERATIONAL-AMPLIFIER WITH A NEW CONSTANT-TRANSCONDUCTANCE INPUT STAGE, HEWLETT-PAC, 48(4), 1997, pp. 114-120
Design trade-offs for a low-voltage two-stage amplifier in the HP CMOS
14 process are presented and some of the issues of low-voltage analog
design are discussed. The design of a new constant-transconductance in
put stage that has a rail-to-rail common-mode input range is described
, along with the rail-to-rail class-AB output stage. The performance s
pecifications and area of this amplifier are compared with a similar d
esign in a previous process, CMOS34.
