Abstract: Amplifiers can be used for a variety of electronic-based applications. Therefore, amplifier performance is of importance. A low noise amplifier can be interfaced after an antenna or a band-select filter as a first active stage, in a receiver since its bandwidth characteristics can be closely related to a system data rate. A bandwidth enhancement technique can be leverage for low noise amplifiers by embedding a transformer between a gate and a drain terminal of a common gate transistor in a cascode topology. The embedded transformer can introduce an additional high-frequency conjugate zero pair, which can push the gain rolling-off start-up point to a higher frequency, peak the higher frequency gain, and broaden the low noise amplifier gain bandwidth.

Abstract: Transistors can be used for a variety of electronic-based applications. Therefore, transistor efficiency and performance is of importance. An apparatus is presented herein to increase the locking range of transistors by leveraging cross-coupled injection transistors in conjunction with symmetry injection transistors. The transistor efficiency can also be increase by reducing a parasitic capacitance associated with the components of the transistor.

Abstract: A pad-free radio-frequency mouse includes an ergonomic design such that the mouse is contoured to a user's hand, a Radio-Frequency mouse transmitter, and a USB Radio-Frequency receiver. With the usual mouse pad removed, the cursor on a monitor can be subtly maneuvered by moving one's thumb or fingers over an optical sensor in the mouse. Practically all functions found in existing mice and new functions can be implemented via five or more buttons provided adjacent the optical sensor.
