Designing flexible electronics has long been constrained by the limits of two-dimensional printing. Now, researchers have ...

The 1K resistor limits the current flowing through the circuit. The 1N4148 diode has a threshold voltage of about 0.7 V. This means that for voltages lower than about 0.7 V at the “out” node, the ...

The instrument described here can be used to measure currents from around 0.1 pA to 1 μA, without the need to change range. One approach is to exploit the logarithmic characteristic curve of a silicon ...

Which of the fixed inductances is actually used is determined by IC3 using the switching circuit comprising 1N4148 diodes D6 and D7, which can effectively short a selected part of the inductance in ...

[MaBe42] used the classic LM358 op amp for most of the circuits, along with 1N4148 diodes where possible and 1N4004s where needed – not for their higher power rating, but for their stronger leads.

Abstract: This paper describes a simple analytical model of the rectifier circuit valid down to very low voltage operation (input voltage below the thermal voltage). Steady-state and transient ...

The Zener diode (red — 1N5245B, trr ≈ 600 ns, Vreset ≈ 14 V) has a little more delay but controlled voltage. The signal diode (grey — 1N4148, trr = 4-8 ns, Vreset ≈ 21 V) is fast and harsh and has a ...
