[Ideas For Design]
Single-supply RS-232 transmission without level-translator ICs
In general, the best way to reduce the price of cost-sensitive consumer products is to lower chip count as much as possible, leaving more tasks to be performed in software. For example, in applications where RS-232 transmission is used... — Contributing Author

DC-AC inverter targets electroluminescent applications
Adc-ac inverter circuit generates the high-voltage ac signal required to drive an electroluminescent (EL) panel. An EL panel is a strip of plastic that’s coated with a phosphorous material. When a highvoltage ac signal, which is at least 40 V or... — Contributing Author

[Ideas For Design]
Use a FET as a linear temperature sensor
In many linear applications of field-effect transistors, the FET is used as a constant-current device for large VDS (i.e., drain-to-source voltage) or as ohmic resistance for small VDS. In the region before pinch-off, the FET is... — Contributing Author
