Assignee:

Silicon Storage Technology, Inc. - Sunnyvale CA

International Classification:

G05F001/10

US Classification:

327539

Abstract:

A bandgap reference generator comprises a PMOS transistor and NMOS transistor in a pnp bipolar junction transistor connected in series in a first leg. The bandgap reference generator includes a second leg that includes a PMOS transistor, an NMOS transistor, a resistor and a pnp bipolar junction transistor. A bias circuit provides a bias to a mirror formed by the gates of the PMOS transistors to lower the operating voltage of the bandgap reference generator. A second biasing circuit may provide bias to the mirror formed of the NMOS transistors. A time-based and a DC bias-based start up circuitry and method is provided.

Abstract:

A multi-operational amplifier system comprises a plurality of operational amplifiers and a controller to configure the plurality of operational amplifiers. The operational amplifiers may be selectively configured to operate individually or in combination with other of the operational amplifiers. The operational amplifiers may have different common node inputs. In one aspect, the different inputs may be selected from groups of PMOS, N-type NMOS and NZ NMOS inputs. The operational amplifiers may include the different inputs that are arranged as differential pairs.
