| titleOfInvention | A DIFFERENTIAL SOURCE FOLLOWER HAVING 6dB GAIN WITH APPLICATIONS TO WiGig BASEBAND FILTERS |
| abstract | A Sallen-Key filter requires an operational amplifier with a large input impedance and a small output impedance. The operational amplifier requires an internal feedback path for stability that limits performance. This invention eliminates the need for internal feedback and increases the gain of a source follower which has characteristics matching the operational amplifier in the Sallen-Key filter. The source follower provides 6dB of AC voltage gain and is substituted for the operational amplifier. The Sallen-Key filter requires a differential configuration to generate all the required signals with their compliments and uses these signals in a feed forward path. Furthermore, a two n-channel stacked device maximizes the headroom voltage to several hundred millivolts for a 1.2V voltage supply in a 40nm CMOS technology. Thus, the required 880MHz bandwidth of the Sallen-Key filter can be easily met using the innovative source follower. |
