Design of piezoelectric actuator based on MOSFET architecture

The production cost of high-speed piezoelectric actuators has become cheaper and cheaper in the past 15 years, so more and more application designs tend to use high-speed piezoelectric actuators. Piezoelectric actuators were originally used in medical devices, including surgical tools and ultrasonic examinations in the late 1980s. This made sense at that time, because the […]

Design of operational amplifier which can absorb and supply current

When designing electronic equipment (such as sensor or amplifier bias power supply or special waveform generator), a controlled constant current source or receiving circuit can be used as a very useful building block. These circuits have high dynamic output impedance and can provide relatively large current in the allowable compliance voltage range. A constant current […]
