A Tunable Quadrature Oscillator with Only Transconductance Elements and Grounded Capacitors
Active networks Transconductance element gm-C oscillators
2010/12/7
A novel quadrature oscillator is realised with only transconductance elements (TEs) and grounded capacitors. The realised quadrature oscillator uses only two inverting and two non-inverting transcondu...
A Novel Coherent Digital Sweep Oscillator with Extremely Low Sweep Rates and Harmonic Distortion
Harmonic distortion Sweep rate Digital sweep oscillators Look-up-table Fractional addressing Interpolation methods
2010/12/8
A novel technique to efficiently increase the resolution of coherent digital sweep oscillators based on look-up-table (LUT) methods is proposed. The increase in resolution measured in terms of sweep r...
