Abstract
The present invention is directed to an apparatus and method for providing a regulated DC output voltage suitable for high power (e.g., high current), high transmission rate systems in a relatively straightforward, cost efficient manner. Exemplary embodiments of the present invention can provide stable DC voltage outputs possessing essentially no AC component over the desired operating voltage range (e.g., at a 5 volt DC output, virtually no AC component over one millivolt range peak-to-peak is present), and possesses a high current capability (e.g., at a 5 volt DC output exemplary embodiments can accommodate currents in excess of 0.5 amps (A) up to 7 A or greater). The ability to provide a very stable, high current capability voltage regulator is especially desirable for communication systems, and in particular, wireless communication systems, wherein transmission rates are on the order of 125 Mb/s or higher, and transmission power is on the order of 0.5 to 2 watts (W) or higher. Because of its high current capability, voltage regulators in accordance with exemplary embodiments of the present invention are suitable for use in conjunction with high power (e.g., 0.5 W) monolithic millimeter wave integrated circuits (MMICs). Exemplary embodiments possess a high signal-to-noise (SB) ratio, and a bit error rate on the order of 10,or lower with 99.99% availability.
