Low Inductance Capacitors

Introduction

The signal integrity characteristics of a Power Delivery Network (PDN)

are becoming critical aspects of board level and semiconductor package

designs due to higher operating frequencies, larger power demands, and the

ever shrinking lower and upper voltage limits around low operating voltages.

These power system challenges are coming from mainstream designs

with operating frequencies of 300MHz or greater, modest ICs with power

demand of 15 watts or more, and operating voltages below 3 volts.

The ESL of a capacitor determines the speed of energy transfer to a load.

The lower the ESL of a capacitor, the faster that energy can be transferred

to a load. Historically, there has been a tradeoff between energy storage

(capacitance) and inductance (speed of energy delivery). Low ESL devices

typically have low capacitance. Likewise, higher capacitance devices

typically have higher ESLs. This tradeoff between ESL (speed of energy

delivery) and capacitance (energy storage) drives the PDN design topology

that places the fastest low ESL capacitors as close to the load as possible.

Low Inductance MLCCs are found on semiconductor packages and on

boards as close as possible to the load.

The classic PDN topology is comprised of a series of capacitor stages.

Figure 1 is an example of this architecture with multiple capacitor stages.

An ideal capacitor can transfer all its stored energy to a load instantly. A real

capacitor has parasitics that prevent instantaneous transfer of a capacitor’s

stored energy. The true nature of a capacitor can be modeled as an RLC

equivalent circuit. For most simulation purposes, it is possible to model

the characteristics of a real capacitor with one capacitor, one resistor, and

one inductor. The RLC values in this model are commonly referred to as

equivalent series capacitance (ESC), equivalent series resistance (ESR), and

equivalent series inductance (ESL).

LOW INDUCTANCE CHIP CAPACITORS

INTERDIGITATED CAPACITORS

The key physical characteristic determining equivalent series inductance

(ESL) of a capacitor is the size of the current loop it creates. The smaller

the current loop, the lower the ESL. A standard surface mount MLCC is

rectangular in shape with electrical terminations on its shorter sides. A

Low Inductance Chip Capacitor (LICC) sometimes referred to as Reverse

Geometry Capacitor (RGC) has its terminations on the longer side of its

rectangular shape.

The size of a current loop has the greatest impact on the ESL characteristics

of a surface mount capacitor. There is a secondary method for decreasing

the ESL of a capacitor. This secondary method uses adjacent opposing

current loops to reduce ESL. The InterDigitated Capacitor (IDC) utilizes

both primary and secondary methods of reducing inductance. The IDC

architecture shrinks the distance between terminations to minimize the

current loop size, then further reduces inductance by creating adjacent

opposing current loops.

When the distance between terminations is reduced, the size of the current

loop is reduced. Since the size of the current loop is the primary driver of

inductance, an 0306 with a smaller current loop has signiﬁcantly lower

ESL then an 0603. The reduction in ESL varies by EIA size, however, ESL is

typically reduced 60% or more with an LICC versus a standard MLCC.

An IDC is one single capacitor with an internal structure that has been

optimized for low ESL. Similar to standard MLCC versus LICCs, the

reduction in ESL varies by EIA case size. Typically, for the same EIA size, an

IDC delivers an ESL that is at least 80% lower than an MLCC.
