Abstract
A MEMS airflow sensor die having a heater control circuit, differential instrumentation amplifier, temperature compensation, and/or offset correction circuitry integrated with an airflow sensor on the MEMS die. The added circuitry may be placed on space available on the basic airflow die with MEMS fabrication techniques without enlarging the sensor die. The die with the added circuitry may result in a device having a reduced form factor, improved reliability and lower cost.
