This sound frequency meter circuit is simple to build and can be constructed in a portable format. In can measure frequencies with a minimum level of 10 mVrms and a maximum frequency of up to 100kHz.

These days, there is a requirement of achieving high frequency targets with lower power consumption ... in power consumption and die size. The proposed circuit is a single supply level shifter to ...

A PLL is overkill for some applications, however, especially if the input frequency needs only to be doubled. For those cases a simpler approach”such as the circuit in Figure 1″ will do the job just ...

Conversely, if the circuit is designed for a low output frequency, then, for a high output frequency ... of the ring oscillator can be small enough that the design of the level shifter after the ring ...

integrated circuit (IC), the new device from the CU team enables simultaneous wireless radio transmission and reception at the same frequency. Dubbed CoSMIC – for Columbia high-Speed and Mm-wave ...

the new phase shifter has a 'phase compensation' technique that provides extremely low phase deviation with frequency over a wide bandwidth. University of Birmingham Enterprise has filed a patent ...

of the Tokyo Institute of Technology, developed a new algorithm and circuit technology allowing high-frequency piezoelectric resonators to be used for phase locked loops (PLL). It was confirmed ...
