Abstract :
An analog synthesizer of orthogonal signals for digital CMOS technology and 3V supply voltage is presented. The adaptive architecture accomplishes the synthesis of mutually orthogonal signals, such as trigonometric and polynomial basis. Experimental results using 0.35 μm AMS CMOS process are presented for generation of the cosine and Legendre basis.
