  1. Simple diode serves as a sensor for a thermal probe
    This 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...

  2. Use a heated diode as a flow sensor
    This 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...

  3. Sub-picofarad measurement with CMOS inverters
    The 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...

  4. Use LEDs as photodiodes
    The 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...
