She sourced a crystal oscillator which runs at 1 MHz ... A toggle switch allows her to choose the crystal, or a 555 timer circuit which uses a push button to fire each clock pulse.

Time crystals represent a new phase of matter proposed by Frank Wilczek, the Nobel laureate of Physics in 2004; they can ...

This is a 32768Hz crystal oscillator specifically designed for ultra-low power application. The sole power supply is 3.3V, but it can be as low as 1.6V while the oscillator can still function properly ...

and a PWM audio over optical transmitter and receiver. If you want to test your understanding of op amps, you can try to analyze the different circuits to see if you can explain how they work.

Arsenal managed to extend the Premier League title race until at least Sunday, but not in the fashion they would have hoped after Crystal Palace ... on Sunday (11:30 am ET) would make it an ...

This circuit demonstrates the potential of driving droplets and supplying effective droplet position feedback for the high-throughput AM-DMF system, enabling the closed-loop droplet control.

Abstract: In this letter, we propose memory in pixel (MIP) circuit that achieves 6-bit depth per sub-pixel, resulting in an 18-bit color depth for RGB displays. The circuit integrates two memory cells ...
