Clock gating is a well-understood power optimization technique employed in both ASIC and FPGA designs to eliminate unnecessary switching activity. This method usually requires that the designers add a ...

The PCF8593 is a CMOS1 clock and calendar circuit, optimized for low power consumption. Addresses and data are transferred serially via the two-line bidirectional I²C-bus. The built-in word address ...

You have to be pretty ambitious to modify a clock to run for 50 years on a single battery. You also should probably be pretty young if you think you’re going to verify your power estimates, at least ...

Over the past two decades, e-paper has evolved from an exotic and expensive display technology to something cheap enough to be used for supermarket price tags. While such electronic shelf labels are ...

The heart of NIST’s next-generation miniature atomic clock ticking at high “optical” frequencies is this vapor cell on a chip, shown next to a coffee bean for scale. The glass cell (the square window ...
