Multi-finger transistor layout is widely used in CMOS circuit designs. Comparing with single-finger transistor layout, its main features include effectiveness in reducing circuit physical size and improving device matching. However in CMOS ring oscillator design, considerable performance discrepancies are found between multi-finger transistor layout and single finger transistor layout. Despite such...
Nanowire MOSFETs have been recognized as one of the possible choices to continue the scaling of CMOS beyond conventional scaling limits. In present study we study various aspects of device characteristics and Mixedmode circuit behavior of Silicon and Germanium Nanowire MOSFETs. The various parameters determining the behavior of device in the analog/digital circuits is studied and compared for Nanowire...
The design of a multiscroll chaotic oscillator based on the realization of a sawtooth function by using floating gate MOSFETs (FGMOS), is introduced. Basically, we propose the implementation of a FGMOS inverter to generate the nonlinear functions which are responsible of the equilibrium points of a continuous chaotic dynamical system, allowing the generation of multiple scroll attractors. Spice simulations...
A circuit-based device noise characterization technique is introduced which uses phase noise data to estimate the power spectral density (PSD) of high-frequency noise in MOSFETs. To apply this technique to a typical CMOS process, an oscillator structure is introduced which provides a predictable phase noise level for a given device noise PSD. The analytical equations governing the phase noise of this...
