20100182086 | SUPER SOURCE FOLLOWER OUTPUT IMPEDANCE ENHANCEMENT - A source follower circuit is disclosed with an added amplifier that extends the low input voltage linear range while providing a lower output impedance. The drain of the source follower MOSFET is coupled to a gain stage that drives a second MOSFET (or other type transistor) with its drain coupled to the follower output. High impedance current sources bias the circuitry, and the difference amplifier has a reference voltage at one input. The difference amplifier with the reference voltage provides a feedback mechanism that maintain adequate drain to source voltage across the follower MOSFET to enhance the low input voltage linearity along with reducing the follower output resistance. | 07-22-2010 |

20110246297 | Systems and Methods for Using Server Side Cookies by a Demand Side Platform - The present disclosure is directed to methods for identifying a user by a demand side platform (DSP) across advertiser exchanges. The method includes establishing, by a DSP, a cookie mapping for a user. The cookie mapping includes a mapping of user identifiers for the user from advertisement exchanges to a user identifier assigned by the DSP for the user. The DSP stores to the cookie mapping a first mapping to the user identifier of the DSP, comprising a first user id received by a bidder from a first exchange and a first exchange id for the first exchange. A bidder inserts a pixel into a bid for an impression opportunity to a second exchange. The pixel includes a key to the cookie mapping and a second user id for the user and a second exchange id. The second user id is received by the bidder from a second exchange. | 10-06-2011 |
