Sine function generator

Abstract

This paper proposes the class of the translinear (TL) circuits implementing a wide range of static nonlinear relationships in the current signal domain to computational such as generating products, quotients, vector magnitude and rational functions, which are implemented in a standard 0.35-μm SiGe technology. A shunt-feedback buffer principle is used in order to regulate its emitter voltage of translinear to generate sinusoidal wave. The resolution can be fine tune by adjusting the output current source. The circuits use no any capacitances and filters. The circuits are based on exploit the exponential current-voltage characteristic of bipolar transistors. The analysis of input, and output resistance and current-gain are depicted. The SFDR of sin wave resolution measurement is 55.23 dB at a 1-MHz and the power consumption is 102mW with the die areas 0.66×0.62 μm2.
