  • Variable clock configuration for switched op-amp circuits
    Patent number: 7203859
    Abstract: A clock configuration for driving switched op-amp circuits operated in opposite phases is presented in which a common off-phase of variable length is inserted between the on-phases of the individual operational amplifiers. The length of the off-phase can be adapted to the transient response of the operational amplifiers used. The clock configuration according to the invention can be used for further reducing the power consumption of switched op-amp circuits.

  • Switchable operational amplifier for switched op-amp applications
    Patent number: 6559716
    Abstract: A switchable operational amplifier is presented for switched op amp technology, in which the current through the pre-stage is reduced during the off phase of the switching clock pulse. In this way, power consumption can be reduced. During the off phase of the switching clock pulse, the current can either be reduced or switched off completely.
