By solving the Landau-Lifschitz-Gilbert equation in the macrospin approach we have analysed the free-layer magnetization dynamics of a perpendicular polarizer — planar SAF free layer spin-torque oscillator at 0K temperature. The current-field state diagram obtained exhibits three different behaviors: a stable in-plane alignment of the two SAF's layers magnetizations for low current densities (J);...
The non-ideal behaviour of a classical comparator-based first-order relaxation oscillator is analysed. The influences of the comparator slew-rate and output resistance as well as the parasitic resistances of the reactive element are considered. Numerical simulations at system level and transistor level are given.
The present circuit uses a simple oscillator structure as a base point for a continuous time chaos generator. The strange attractor and chaotic behavior was demonstrated by several implementations of the circuit: mathematical model (calculated using specialized software), SPICE simulation and hardware implementation.
A clock generating system for USB 2.0 with an enhanced bandgap reference circuit is proposed to replace an external crystal oscillator. To comply with clock frequency and long term jitter specifications under high supply noise, the power supply of the DCO is regulated by a low drop-out regulator. The reference voltage for the LDO is generated by the bandgap reference circuit with two bandgap cores...
