  1. Differential temperature measurement is a handy way to quantify the performance of heatsinks, thermoelectric coolers (TECs), and thermal control in electronic assemblies. Figure 1 illustrates an inexpensive design for a high-resolution differential ...

  2. Conventional thermostats are based on separate temperature sensor and heater devices with means for feedback between them. But in some recent EDN design ideas (DIs) we’ve seen thermostat designs that meld the functions of sensor and heater ...

  1. Evaluating analog switches, multiplexers, operational amplifiers, and other ICs poses challenges to IC-test engineers. A typical test scenario requires application of a test or forcing voltage to a device's input and measurement of any ...

  2. Avoiding op-amp output saturation error by keeping op-amp outputs “live” and below zero volts is a job where a few milliamps and volts (or even fractions of one volt) of regulated negative rail can be key to achieving accurate analog ...

  3. Awhile back I published a simple design idea for a thermal airspeed sensor based on a self-heated Darlington transistor pair ( Ref. 1 ). See Figure 1. Figure 1. Older design idea with self-heated Darlington thermal airflow sensor. In the circuit, ...

  4. A classic analog application is the full-wave precision rectifier (absolute value) function. Many variations exist on this theme, each with its own supposed (often rather minor and sometimes downright dubious) advantages compared to competing ...

  5. A question that arises frequently in audio and signal processing applications is this: How can I control gain on dual channel (e.g., stereo) inputs simultaneously with only a single knob? Of course, an obvious solution would be to simply use a dual ...

  6. “The unfortunate relationship between servo systems and oscillators is very apparent in thermal-control systems,” said Linear Technology's Jim Williams ( Reference 1 ). Although high-performance temperature control looks simple in ...

  7. A good manually adjusted audio gain stage is characterized by: Low noise and low distortion, A 20 kHz bandwidth, A wide gain adjustment range (e.g. 90 dB), and Logarithmic (at least pseudo-logarithmic) control characteristic to Efficiently span ...

  8. There are several applications in which pulses longer than the set width are to be detected, ignoring the other short pulses. We are familiar with the missing pulse detector circuit, which detects the occurrence of a missing pulse in a pulse train ...
