This paper reviews and analyzes two reported image-rejection (IR) low-noise amplifier (LNA) design techniques based on CMOS technology, i.e., the second-order active notch filer and third-order passive notch filter. The analyses and discussions are based on the quality factor of filters and the ability of the frequency control. As the solution to deal with(More)
Motivated by the huge data transmission capacity required for multimedia communications, passive optical network (PON) based on fiber-to-the-home (FTTH) is considered an emerging access network technology to solve the last mile problem of communications. A typical PON system is basically a point-to-multipoint (PtMP) optical network with no active elements(More)
A high-speed and low power transimpedance amplifier for 2.5Gb/s applications has been implemented in 0.35μm CMOS technology. For higher transimpedance gain and wider bandwidth, in this paper, an inductive shunt peaking technique is applied using a novel active inductor load that can be used at 1 ~ 2GHz range. Measured performance shows 1.45GHz bandwidth(More)
