Abstract
To develop and implement a wideband body enabled front end transceiver for use in 0.18 µm. The front end transceiver implementation for this thesis will consist of the common first two devices which are the LNA and mixer. The LNA is the first device from antenna which is there to amplify the signal received from the antenna. The mixer is there to take the next step which is to mix the amplified signal from the LNA and mixer it with the signal from the local oscillator (usually a PFD). The wide range of operation for both LNA and mixer will be from 4 - 12.5 GHz. The range of operation will require that over the range the input and output matching must be less than -10 dB. The gain of the LNA must be over 10 dB while the passive mixer will not have any gain therefore the goal will be to get the gain as close to zero as possible. The noise of the LNA should never get above 5 dB at any point during the range of operation. The noise of the mixer will be comparable to previously published papers where the noise is around 9 - 14 dB. The LNA will implement forward body bias voltage applied to the body of the transistors to reduce the voltage required and current through the LNA and therefore saving power while maintaining the specifications of the LNA. The mixer will implement body driven topology in which the amplified signal from the LNA will be applied to the body terminal therefore allowing the mixer to achieve better results than if the amplified signal was coming through drain of the transistors. Overall the design of the LNA is a completely new idea that has never been researched before and will allow for the LNA to achieve a wide range of operation while reducing the voltage supply. The mixer is a concept adapted from a published paper and developed for a new mixer topology and will allow for increased results and better range of operation than previously published papers.
