Using CMOS gates to generatepulses sometimes causes timinguncertainty due to gate-threshold variations.For accurate pulse widths, youcan use BJTs (bipolar-junction transistors).Basing the design on ...

Unijunction transistors (UJTs) were common circuit elements several decades ago. A simple ramp generator could be built from a single UJT and a few other components (Fig. 1). 1. In a simple UJT-based ...

Current monitoring has become simpler because of the availability of dedicated integrated circuits. Current monitoring integrated circuits are readily available and under most circumstances do an ...

Emerging large-area technologies based on organic transistors are enabling the fabrication of low-cost flexible circuits, smart sensors and biomedical devices. High-gain transistors are essential for ...
