“…The sensors also cannot operate at high temperatures. A differential charge amplifier can effectively reduce the influence of sensor capacitance and cable capacitance on measurement accuracy [79] PZT, a kind of inorganic material, is the industrially most commonly used piezoelectric material [76]. It has stable performance, with a high dielectric constant and piezoelectric coefficient.…”

Micro-force measurement with high resolution, accuracy, and reliability is of interest to a broad range of applications including gravitational wave detection, intelligent healthcare, bionic robot, and micromanipulation. Herein, the research development in recent years of micro-force sensors based on various principles is reviewed thoroughly, presenting the characteristics and applications, as well as summarizing their advantages and limitations. The indispensable component of force sensors, elastic sensitive elements, is underlined. Next, four kinds of not widely used but promising sensors are also introduced briefly. Finally, the traceable reference forces are analyzed, concluding with a future perspective into the corresponding challenges and opportunities of micro-force sensors for future research. This review aims at providing references for developing micro-force sensors and improving their performance.

“…R f can be implemented with MOS transistors to reduce area and provide greater design flexibility [60]. The offset, bandwidth, power consumption, dynamic range, and gain of CSP, are functions of the feedback components [44,48,61,62]. Figure 5 shows a comparison of the gain and bandwidth of characteristics of a few implemented charge amplifiers.…”

Silicon photomultipliers (SiPMs) offer advantages such as lower relative cost, smaller size, and lower operating voltages compared to photomultiplier tubes. A SiPM’s readout circuit topology can significantly affect the characteristics of an imaging array. In nuclear imaging and detection, energy, timing, and position are the primary characteristics of interest. Nuclear imaging has applications in the medical, astronomy, and high energy physics fields, making SiPMs an active research area. This work is focused on the circuit topologies required for nuclear imaging. We surveyed the readout strategies including the front end preamplification topology choices of transimpedance amplifier, charge amplifier, and voltage amplifier. In addition, a review of circuit topologies suitable for energy, timing, and position information extraction was performed along with a summary of performance limitations and current challenges.

“…Previous works for ready-to-use preamplifiers were focused on high voltage designs for power electronics and automotive applications [3,4]. Some other board-level implementations were designed to target specific applications such as charge amplification for conditioning of piezoelectric sensors [5]. Specific designs for low noise and fast event detection [6] or low frequency/low voltage measurements [7] were also proposed.…”

Acquisition of differential signals from low voltage and high impedance sources is difficult when using commonly available laboratory test equipment such as a standard oscilloscope or single ended acquisition system. This paper presents a versatile differential preamplifier for universal signal conditioning. The probe offers a wide input voltage range and can measure signals ranging from a few hundred micro-volts up to 100 V with 1 MHz bandwidth. It also contains a programmable output filter for bandwidth limitation and noise reduction, user-accessible controls for offset adjustment and input coupling mode selection. The probe can be powered through an USB port or by using an internal battery. Input impedance can be made virtually infinite by the JFET input stage, which makes this differential preamplifier usable with a variety of high-impedance sources commonly encountered in the sensors research field and in electronic engineering. Experimental validation shows that the proposed device has better performance levels and interoperability than commercially available instrumentation at a reduced cost, even while using off-the-shelf components.
