- Two wires carry power and dataAt times, designers face a limited amount of wire and/or a limited cost to communicate with a remote device such as a sensor. Many devices allow communication over an ac or dc power line employing an AM or FM modulation scheme. However, they tend to be costly. This...07-02-2023
- Create A 12-V Split Rail From A 5-V BiasWith digital semiconductor technology driving system power supplies to lower voltages for higher performance and lower system power, sensitive analog sensor circuits face a growing problem. Much of the inherent noise created in the early stages of an analog sensor signal path is...08-11-2019
- Voltage Reference Bests Zener Diode as Low-Current Bias SourceZeners are commonly used as low-current sources for bias voltage functions, but the proper voltage reference can give the same result and with much-lower dissipation and no performance tradeoffs. There are times when you need to bias a low-current load and simply didn’t...20-12-2018
