Oscillations in power electronic circuits with fast switching semiconductors are commonly known and the corresponding parasitic elements have been investigated in multiple literature. However, this paper investigates the triggering of these electromagnetic interference (EMI)-critical oscillations. An analytical description is derived using a boost converter circuit. Based on this description an optimization...
Noise-aware Design, statistical modeling analysis and experimental verification of crystal oscillators fabricated using advanced SiGe-C BiCMOS technology are presented. The concept of Broadband stochastic equivalent circuit models extraction is introduced to properly account for variability and sensitivity of critical design parameters (e.g., Process, Power Supply, Temperature, Geometry). Engineering...
In this paper, we present an analytical model for a CMOS LC tank oscillator with its active devices operating in weak inversion. Our model combines nonlinear, stochastic circuit analysis in the form of the so-called stochastic averaging method proposed by Stratonovich with advanced MOS device modeling in the form of the EKV-model. The presented approach not only provides — for the first time — simple,...
Simultaneous switching noise (SSN) is an important issue for the design and test and actual ICs. In particular, SSN that originates from the internal logic circuitry becomes a serious problem as the speed and density of the internal circuit increase. In this paper, an on-chip monitor is proposed to detect potential logic errors in digital circuits due to the presence of SSN. This monitor checks the...
The next generation of wireless communication is a ubiquitous radio system concept, providing wireless access from short-range to wide-area, with one single reconfigurable and adaptive system for all envisaged radio environments. This paper presents the design approach of RCO (reconfigurable concurrent oscillator) that simultaneously generates two or more signals of different frequencies that eliminate...
