Flyback Converter Without Opto-Isolated Feedback
Do you know which side of the galvanic isolation to put the controller? Should you use optocouplers or some other method? Find out here.
Interactive A/D mixed signal modeling via Foreign VHDL/Verilog C
In this article an analog-digital mixed signal modeling approach based on the conversion of analog Matlab/Simulink® model to C code is presented, along with a real case study.
GaN-on-SiC amplifier operates at up to 2.7GHz
The QPD2731 addresses the shift towards gallium nitride on silicon carbide (GaN-on-SiC) with pre-matched, discrete GaN-on-SiC high electron mobility transistors.
26-bit ADC boosts CT scan resolution
