ABSTRACT:

BACKGROUND
The invention generally relates to a supply voltage regulation system,
A typical computer system may include a supply voltage delivery system, such as a voltage regulation system
5
that is depicted in
FIG. 1
, for purposes of communicating a supply voltage to power consuming circuitry of the computer system. As an example, this power consuming circuitry may be distributed throughout the system on various dies that form the components of the system. More particularly, as depicted in
FIG. 1
, the voltage regulation system
5
may include a voltage regulator module (VRM)
10
that furnishes a supply voltage (called V
DC
), a voltage that is communicated to the power consuming circuitry
16
of a particular die
14
via a transmission line
12
.
Ideally, the transmission line
12
has zero resistance, inductance and capacitance. However, such characteristics for the transmission line
12
are usually not the case, as the transmission line
12
may be subject to various parasitic elements. For example, there are parasitic impedances such as resistances and inductances that may be introduced to the transmission line
12
through semiconductor package(s), socket/connector(s) and motherboard traces. Furthermore, the transmission line
12
may be subject to various parasitic capacitances due to these same elements, as well as be subject to capacitances that are contributed by coupling capacitors.
Due to these non-ideal effects, it is possible that a voltage drop, or “droop,” may occur across the transmission line
12
. In this manner, during times of relatively high power demand from the transmission line
12
, a significant difference may exist between the V
DC
voltage at one end of the transmission line
12
and the voltage that appears at the supply voltage pin of the die
14
at the other end of the transmission line
12
. For purposes of compensating for a momentary voltage droop, one or more capacitors
13
may be coupled between the transmission line
12
and ground. These capacitors
13
serve as energy storage devices to stabilize the voltage present at the supply voltage pin of the die
14
. However, a difficulty with this voltage droop compensation scheme is that the capacitor(s)
13
may be relatively inefficient and introduce significant power losses.
Thus, there is a continuing need for an arrangement that addresses one or more of the problems that are stated above.
