LRF – Laboratório de Pesquisas em Radiofrequências

     Today, the graduate student Roddy Romero defended his master’s thesis entitled “Duty-Cycle Controlled Variable-Gain”.

This month, the graduate student Roddy Romero presented his work on low-power biopotential front-ends  during the joint meeting between our group and the UFSC Embedded Systems Group (GSE). (See his presentation)

Graduate and undergraduate students of our group participated of the main Brazilian conference  on microlectronics. The Chip in Brasília 2012 was s a joint event promoted by the Microelectronics Brazilian Society(SBMICRO) and Computer Brazilian Society (SBC/CECCI).

Our students presented three works:

• A 40 mV/4 uW CMOS Colpitts Oscillator With Additional Positive Feedback at 2.12 GHz. (See the work)
• Design Methodology for Class-E Power Oscillators. (See the poster)
• A 2.4 GHz Cascode CMOS Low Noise Amplifier. (See the work)

New LNA designs were successfully characterized at our lab!

Our breakthrough work on low voltage electronics was presented at ISCAS 2012 / Seoul: “A 20 mV Colpitts Oscillator powered by a thermoelectric generator”. (poster pdf)
