    Figure 1’s silly-simple voltage-to-time ADC is an exercise in dynamic range. Assuming that it is used with a 10-MHz counter/timer, its resolution is roughly 10 µV per count for inputs around 0 V and 100 mV per count at 1 kV, and it ...

    Figure 1 is a cheap and cheerful voltage inverter I offered awhile back in “A simple, accurate, and efficient charge pump voltage inverter for $1” ( Ref. 1 ). Figure 1. The generic and versatile xx4053 provides the basis for a cheap, ...

    ADC circuits that resolve signal into 20 or more bits need a low-noise signal source for measuring parameters such as harmonic distortion or effective number of bits. A notch filter removes the fundamental frequency from the oscillators signal for ...

    Mystery solved? Not quite. I made a test coupon of the output transmission line and measured it. Over the crossover region, it showed a mere 0.04 dB loss with increasing frequency, much less than the measured result. I turned my attention back to ...

    Students, hobbyists, and professionals today enjoy unprecedented access to powerful and affordable test equipment for understanding and building electronic projects. But as enthusiast projects have become more advanced and ambitious, it is still ...

    This circuit is a simple sweep generator. The sawtooth is generated by the PNP transistor and the 555 . The transistor together with the 2 diodes at the base form a constant current source which charges the 330 nF capacitor. If 2/3V CC (=6 V) is ...

    This dummy-load circuit has been in use at Maxim for more than 10 years (see the Figure 1). It's useful for testing power supplies and power amplifiers as well as drivers for LEDs, relays, and solenoids. Plus, it overcomes the limitations of ...

    I was surprised recently when a (nearly) two-decade-old design idea of mine for take-back-half temperature control ( Ref. 1 ) got a question from reader John Louis Waugaman. John says he needs a way to control the temperature of batches of rising ...

    The excellent linearity of integrated-circuit temperature sensors makes them ideal for direct analog compensation of the thermally induced errors inherent in many circuits. For example, a negative-sloped temperature sensor could compensate for an ...

    Usually, noise annoys. Occasionally, it can be a valuable tool. Surprisingly, there is a whole palette of noise colors [ 1 ]. This design idea (DI) shows good ways of generating the commonest and most useful ones, which are white [ 2 ] and pink [ 3 ...
