ANALOG FRONT-END ARCHITECTURE FOR CAPACITIVE PRESSURE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18258762 titled 'ANALOG FRONT-END ARCHITECTURE FOR CAPACITIVE PRESSURE SENSOR
Simplified Explanation
The analog front-end architecture for a capacitive pressure sensor includes a low-noise amplifier unit with first and second integrator units, a feedback unit, and a startup unit.
- The first and second integrator units integrate charges injected into the input terminals and output integrated charges to the output terminals.
- The feedback unit reinjects integrated charges from the integrator units back into the input terminals.
- The startup unit can switch between two states to route charges either through the first integrator unit and then the second integrator unit, or directly into the first integrator unit.

Original Abstract Submitted
An analog front-end architecture for a capacitive pressure sensor with a low-noise amplifier unit for amplification of sensor signals from the sensor. The amplifier unit includes first and second integrator units for integrating charges injected into input terminals of the amplifier unit and for outputting integrated charges to output terminals of the amplifier unit, a feedback unit, and a startup unit. The feedback unit reinjects integrated charges from the integrator unit into the input terminals of the amplifier unit. The startup unit is switchable between first and second switching states and is configured, in the first switching state, to route the charges injected into the input terminals past the first integrator unit into the second integrator unit and from the second integrator unit into the feedback unit, and, in the second switching state, to route charges injected into the input terminals directly into the first integrator unit.
