TI technology extends flight time and battery life of quadcopters and industrial drones
TI technology extends flight time and battery life of quadcopters and industrial drones
30.01.2017 · News
Texas Instruments introduced two circuit-based subsystem reference designs that will help manufacturers add flight time and extend battery life to quadcopters and other non-military consumer and industrial drones used to deliver packages, provide surveillance or communicate and assist at long distances...
High-fidelity triangle-wave generator consumes only 6 µA
High-fidelity triangle-wave generator consumes only 6 µA
29.01.2017 · Circuits
Ideal triangle waves involve infinite d2V/dt2, so high-fidelity triangle waves entail very high bandwidths. Micropower circuits have fairly low bandwidth, so generating good triangle waves with such circuitry becomes problematic. The circuits show two methods of generating triangle waves...

AC line powers microcontroller-based fan-speed regulator
AC line powers microcontroller-based fan-speed regulator
24.01.2017 · Circuits
A microcontroller requires dc operating power in the 2 to 5.5 V range, an amount that a battery or a secondary power source can easily supply. However, in certain situations, a microcontroller-based product must operate directly from a 120 or 220 V-ac power outlet without a step-down transformer or a heat-producing, voltage-decreasing resistor...
1-Hz to 100-MHz VFC features 160-dB dynamic range
1-Hz to 100-MHz VFC features 160-dB dynamic range
24.01.2017 · Circuits
The VFC (voltage-to-frequency-converter) circuit achieves a wider dynamic range and a higher full-scale output frequency – 100 MHz with 10% overrange to 110 MHz – by a factor of 10 over any commercially available converter. The circuit's 160-dB dynamic range spans eight decades for a 0 to 5 V input range and allows continuous operation down to 1 Hz...
