A cell phone is provided having multiple sensors configured to detect and measure different parameters of interest. The cell phone includes at least one monolithic integrated multi-sensor (MIMS) device. The MIMS device comprises at least two sensors of different types formed on a common semiconductor substrate. For example, the MIMS device can comprise an indirect sensor and a direct sensor. The cell phone couples a first parameter to be measured directly to the direct sensor. Conversely, the cell phone can couple a second parameter to be measured to the indirect sensor indirectly. Other sensors can be added to the cell phone by stacking a sensor to the MIMS device or to another substrate coupled to the MIMS device. This supports integrating multiple sensors such as a microphone, an accelerometer, and a temperature sensor to reduce cost, complexity, simplify assembly, while increasing performance.
