A complementary metal oxide semiconductor (CMOS) transconductor based on a high performance unity-gain buffer driving the degeneration resistor was used to obtain a highly linear voltage-to-current conversion with c...
A quadrature mixer with a shared transconductor stage is analyzed,including voltage conversion gain, linearity, noise figure, and image rejection. The analysis indicates it has better performance than a conventional G...
An improved structure of linear transconductor is presented in this paper. It is analyzed in theory and simulated with Spectre based on 0.25μm CMOS process. The simulation results show that the differential input vol...
