This paper introduces the notion of profile-based cooperation as a way to support awareness and informal communication between mobile users during chance encounters. We describe the design of Proem, a wearable system for profile-based cooperation that enables users to publish and exchange personal profile information during physical encounters. The Proem system is used to initiate contact between...
An inductive feedback approach for BW extension of transimpedance amplifiers has been proposed. The effect of parasitic capacitances of the MOS transistor has been reduced using this approach. The process of zero-pole cancellation to extend the BW of the amplifier has been explained. To demonstrate the feasibility of the technique a new transimpedance amplifier has been simulated in a well-known CMOS...
