Flatness Improvement for a Shunt-peaked Ultra-wideband Low Noise Amplifier

A novel configuration to achieve flat gain in wideband low noise amplifiers (LNA) is presented. It consists of a conventional shunt-peaking resistor, decoupled from the cascode stage through a capacitor. A trade-off between the voltage headroom and ban...
Ultra-wideband (UWB) is a technology for transmitting information spread over a large bandwidth that should be able to share spectrum with other users. This is the main reason why UWB has attracted much attention from the wireless community, both from standardization bodies and chip manufacturers. The UWB frequency range...
