Analyzing the IO Ring •Build and Simulate a Spice model of the IO ring including: Accurate but Simplified Ring Parasitics Significant Package Parasitics and Terminations Full Spice IO Buffer Models Lots of Measure Statements for all Outputs and Power and Ground Voltages and Currents •Simulate in Spice and Analyze Results

By understanding the causes of IO ring simultaneous switching noise and ground bounce failures, it is easier to make engineering decisions which will correct problems found by the simulations.

RING Designer allows the user to easily specify the full SPICE circuit parameters of the planned ring design including I/O buffer SPICE circuits, power ring sizes, and locations of by-pass capacitors, voltage supply pads and I/O buffers.

2016年1月1日 · A design for a Voltage-controlled ring oscillator (R-VCO) is presented using 0.18um CMOS technology and 3.3 V power supply. The VCO topology exhibits tuning range from 8 MHz to 454 MHz and features the low power dissipation of 0.42mW at the maximum oscillation frequency. Phase noise measured for simulated circuit is -80dBc/Hz at 1 MHz.
