basic information
Operation Description: This device is configured as a quasi-complementary amplifier using MOS-type FETs in the output stage, achieving stabilization of gain and low noise wideband performance through a negative feedback circuit. The input signal is buffered and enters a gain adjustment circuit for gain setting. Meanwhile, the bias voltage generated by a temperature-compensated reference voltage generator can be set to any value using a bias voltage adjuster and is added to the aforementioned signal before entering the output amplifier. The output amplification section receives the input signal through an operational amplifier, and to achieve high output, eight MOS-type FETs are connected in parallel, further reducing impedance through a quasi-complementary circuit. Negative feedback is implemented by returning an inverted signal to the operational amplifier in the input section, and the output terminal is designed to cut off the output in case of overcurrent protection during overcurrent conditions.

Company information
"Mechatrans" is a technology that I developed during my time at NEC in the 1980s, successfully realizing the world's first and fastest piezoelectric impact printer at that time. Subsequently, due to the evolution of printer technology, this technology disappeared from the public eye. However, Professor Toshio Higuchi from the University of Tokyo foresaw the potential of this technology, leading to the establishment of today's company. By leveraging the numerous advantages of the piezoelectric method, "Mechatrans" has achieved high-speed and large-displacement actuators, and I feel the potential for its use in a wide range of fields. We have now developed a series of actuators for everyone’s use.
