Stepper motors are mostly driven in open loop mode. Timing of the step pulses is defined by the controller, the motor is supposed to follow without loosing synchronism. Stepper motors are in fact natural positioning devices which do not require position feedback. The drawback of their design are important iron losses when...
HPC (High Performance Computing) processors and memory loads continue to increase power demands at lower voltages while performance density and total cost of ownership challenges increase.
Efficient HV (high voltage) AC or DC distribution and power conversion to the loads are essential to maximize datacenter...
This paper shows the need for a new impulse response model and proposes a methodology for its inclusion in timedomain simulations.
The paper also solves another difficult problem by presenting a new technique for converting band-limited S-parameters into ‘base-delay’ causal and passive impulse response...
The BMI160 is a small, low-power, low-noise 16 bit Inertial Measurement Unit designed for use in mobile applications such as augmented reality or indoor navigation which require highly accurate, real-time sensor data. In full operation mode, with both the accelerometer and gyroscope enabled, the current consumption is...
Analog Devices’ new RF and microwave (MW) switch and attenuator products implemented in advanced silicon process benefit inherent advantages of silicon technology compared to legacy counterparts using gallium-arsenide (GaAs).
