- Detect wire breaks with unusual CMOS gate circuitCMOS devices have large input impedance with input currents on the order of 0.01 nA. Adding feedback circuitry can result in a latch-like device that can be used to store bits, and also operate in a more analog...08-01-2023
- Simple diode serves as a sensor for a thermal probeThis Design Idea describes a two-transistor thermal probe for diagnosing circuit problems, such as hot components and thermal runaway. Although the probe does not provide an accurate temperature measurement, it acts as...21-11-2022
- Use a heated diode as a flow sensorThis Design Idea describes a method by which you can detect and assess air or liquid fluid flow using an externally heated semiconductor diode. Airflow across the heated diode reduces its temperature, causing a...11-11-2022
- Sub-picofarad measurement with CMOS invertersThe inverters in a CMOS CD4069 can be used for both analog as well as digital applications. This Design Idea illustrates this by using all six inverters in a 4069 package to make a closed loop, duty-cycle-based...09-03-2022
- Use LEDs as photodiodesThe simple circuit in Figure 1, which can be powered with a 3.6 V nickel-cadmium rechargeable battery, lets you use an LED to detect light. The circuit consumes practically no quiescent power. Two LEDs act as...08-03-2022
