The textbook "Integrated Front-end Analog Circuits for MEMS Sensors" by Muhammad Qureshi provides a comprehensive analysis and innovative approaches to enhancing the performance of MEMS sensors, particularly in intravascular ultrasound imaging. It addresses the challenges posed by the miniaturization of sensors, such as the ratio of active to parasitic components, which can affect sensitivity. The book introduces the capacitive feedback charge amplifier as a promising alternative to the resistive feedback amplifier, offering high sensitivity, low distortion, and energy savings. Additionally, it discusses the advantages of optical detection in biomimetic microstructures that overcome thermal noise in capacitive detection. The work also tackles the challenges of energy efficiency in hearing aids and proposes the use of a 1-bit front-end sigma-delta ADC to optimize overall performance. The circuit techniques presented aim to maximize signal processing at low voltages.
