摘要： A charge pump system uses a helper pump to use in generating a boosted clock signal to use for the stages capacitor of a charge pump and also for the gate clock of the stage. This can be particularly useful in applications with lower supply levels, where a the helper pump can be used to provide an amplitude higher than the supply level, that can then be added to the supply level for the boosted clock signal and then added again to the supply level for the gate clock. Further advantages can be obtained by using the helper or auxiliary pump as an input to an optimized inverter circuit that receives an input clock and has an output that initially rises to the supply level than subsequently to the auxiliary pump's level.

摘要： A bandgap reference circuit is compensated for temperature dependent curvature in its output. A voltage across a diode with a fixed current is subtracted from a voltage across a diode with a proportional to absolute temperature (PTAT) current. The resultant voltage is then magnified and added to a PTAT voltage and a diode's voltage that has a complementary-to-absolute temperature (CTAT) characteristic, resulting in a curvature corrected bandgap voltage.

摘要： An analog majority voting circuit is formed of a cascade of two differential amplifiers and decouples heavily loaded nodes from a high voltage swing nodes, delivering high bandwidth while maintaining relatively high gain. A first stage's differential amplifier receives a first set of n input and a second set of n inputs and generates from these first and second intermediate outputs with a high capacitive load and low swing. These intermediate outputs are then the inputs for a second stage's differential amplifier, providing a low capacitive load, high swing output that can then be fed to an inverter for the final output of the voter.
