This article discusses the low current input circuit ideas using the 6N139 series optocouplers. A few of the circuit designs are signal detection, transient detection, matrices and non-loading line ...

A modification of the current-control circuit in a low-voltage LED system allows use of a chopped supply voltage to modulate the LED intensity. The circuit prevents inrush current to the decoupling ...

If your system's signal processing requirements in-clude peak detection and amplification, consider a simple circuit that will satisfy both needs and save hardware. The single-supply circuit shown in ...

Figure 1 demonstrates a one-way switched-capacitor gain stage circuit, performing a voltage gain of AO = ­C1/C2 only during the decreasing trail of the input signal Vi (with VJ... After the reset ...
