“…An HP4291 is used to measure capacitor ESR by soldering it to an SMA connector and attaching it to a test head through an APC-7 connector. Measurements using a traditional surface mount test head may underestimate the actual ESR [5]. ESR and contact resistance are hard to separate and a portion of the ESR may be lost during the compensation process.…”

Power systems for modern complementary metaloxide-semiconductor (CMOS) technology are becoming harder to design. One design methodology is to identify a target impedance to be met across a broad frequency range and specify components to meet that impedance. The impedance versus frequency profiles of the power distribution system components including the voltage regulator module, bulk decoupling capacitors and high frequency ceramic capacitors are defined and reduced to simulation program with integrated circuit emphasis (SPICE) models. A sufficient number of capacitors are placed in parallel to meet the target impedance. Ceramic capacitor equivalent series resistance (ESR) and ESL are extremely important parameters in determining how many capacitors are required. SPICE models are then analyzed in the time domain to find the response to load transients.

“…This is 0.34% of the output power and these resistances are based on a relatively large air core inductor. The equivalent series resistance (ESR) of a ceramic capacitor in the sizes used here will be less than 200 mΩ [30] and the currents running through them are smaller than the current in the inductor. The loss caused by them will thus not be significant.…”

This paper presents the design of a resonant converter with a switching frequency in the very high frequency range (30-300 MHz), a large step down ratio (ten times), and low output power (1 W). Several different inverters and rectifiers are analyzed and compared. The class E inverter and rectifier are selected based on complexity and efficiency estimates. Three different power stages are implemented; one with a large input inductor, one with a switch with small capacitances, and one with a switch with low on-resistance. The power stages are designed with the same specifications and efficiencies from 60.7-82.9% are achieved.

“…To help an engineer to design a PDN for best performance, Smith, [10][11] [12], developed the Frequency Domain Target Impedance Method (FDTI). This method involves choosing the right number of decoupling capacitors of each value such that the parallel combination of those capacitors approximates the target impedance.…”

For a good reliability, the Power Distribution Network (PDN) should meet target impedance across the frequency range of direct current, up to the highest frequency of interest. Using decoupling capacitors is a good mean to maintain the impedance of a PDN below a specified level, [3][4][5].Decoupling capacitors are used to obtain low power supply impedance in the MHz range. Decoupling capacitors have traditionally been modeled as a series RLC network. Capacitors vendors describe the specifications in terms of its capacitance, equivalent series inductance and equivalent series resistance. The RLC components are constant with frequency and are easily identified in the Bode plot. There are several commercial tools available to help in selecting the decoupling capacitors, but the goal of this paper is to present a MATLAB tool that helps us reduce the time of simulations and optimize the process of selecting the decoupling capacitors.
