Abstract: A reference current generator circuit suitable for low-voltage applications is provided. The generator circuit is fabricated in a chip for generating a precise reference current based on a precise reference voltage and a precise external resistor. The generator circuit provides an equivalent resistance coupled in parallel with the external resistor to provide resistance compensation and reduce the impedance of seeing into the chip from a chip pad. In addition to the resistance compensation, only moderate capacitance compensation is required to enhance the phase margin of the generator circuit, so as to achieve a stable loop. Therefore, chip area and cost can be reduced in low-voltage applications. In addition, the generator circuit reproduces the reference current generated by the external resistor by utilizing current mirrors, so as to eliminate the effect on currents caused by parallel coupling of the equivalent resistance and the external resistor.

Abstract: A rivet fixing device includes a catch tab retainer tube engageable with a transmission spindle of an electrically-operated, pneumatic or battery-powered electric drill or screwdriver, an inner guide sleeve, a driver, pawls, a rivet breaker, and an outer guide sleeve. By being driven by the transmission structure of the electric screwdriver, a rivet, with a shank section thereof inserted into a front end of the rivet breaker and the rivet being fit through holes defined in steel plates, iron plates, copper plates, or aluminum plates, due to the catch tab retainer tube being depressed inward to engage the transmission spindle, is driven by the rearward movement of the catch tab retainer tube to have a fit end thereof that extends beyond the holes of the plates squeezed and deformed to form an expanded portion, serving as a positioning wall that stretches and secures the rivet between the two metal plates.

Abstract: A deglitch circuit including signal transmission units is provided. The signal transmission units are connected in serial to form a signal transmission unit string, and a first signal transmission unit of the signal transmission unit string receives a digital signal. Each signal transmission unit includes a first switch, a first delay circuit and a second switch. First and second terminals of the first switch are coupled to a previous signal transmission unit of the signal transmission unit string and an input terminal of the first delay circuit, respectively. The second switch is coupled between an output terminal of the first delay circuit and a first voltage. When the digital signal has a first logic state, the first switch is turned off, and the second switch is turned on. When the digital signal has a second logic state, the first switch is turned on, and the second switch is turned off.
