Master’s degree in Electrical Engineering from University of Southern California (Los Angeles) with specialization in RF design, VLSI and Analog Integrated Circuits. RFIC transceiver design, Analog ...
Microwave frequency generation has posed significant challenges to engineers over the years, requiring in-depth knowledge of analog, digital, and radio frequency (RF) and microwave ...
Phase lock loops (PLLs) play a key role in today's thriving RF industry. Commonly employed to address various timing requirements in ASIC designs, these basic building blocks allow designers to ...
Fig 1. Two analog multipliers form a VCO with quadrature outputs, while a third multiplier provides AGC to stabilize output voltages without adding distortion. Fig 2. The oscilloscope trace of the VCO ...
In this session of Logic Noise, we’ll be playing around with the voltage-controlled oscillator from a 4046 phase-locked loop chip, and using it to make “musical” pitches. It’s a lot of bang for the ...
HSINCHU, Taiwan--Feb. 21, 2006--UMC (NYSE:UMC)(TSE:2303), a world leading semiconductor foundry, today announced that it has fabricated a push-push Voltage-Controlled Oscillator (VCO) with an ...
Voltage-controlled oscillator-based analog-to-digital converters (VCO-based ADCs) represent an emerging class of digitisation circuits that harness the frequency-modulating properties of VCOs to ...
Fig 1. This basic VCO/waveform generator IC circuit includes a voltage follower loop (formed with IC1) and symmetry feedback loop (IC3) to eliminate an asymmetric duty cycle, which would cause ...
Editor’s Note: The author describes the design of a low power, high speed differential to single-ended converter circuit that uses a novel feedback technique to achieve high bandwidth without ...
