|Title:||Analog Triangular-to-sine Converter Using Lateral-pnp Transistors In Cmos Process|
|Abstract:||This paper focuses on the development of a monolithic analog triangular-to-sine converter that is based on the same technique as that devised by Barrie Gilbert , which exploits the fact that a hyperbolic-tangent series converges to the sine. The novelty in the herein-described circuit is the implementation of the sine shaper in CMOS process using lateral-pnp bipolar transistors. Due to the excellent performance of the used lateral-pnp transistors at low current levels, the elected circuit implementation is mostly appropriate for low-power operation. Experimental results from prototypes of the circuit fabricated in 0.6(μm CMOS have shown that the deviation from ideal sine over the -π/2 to π/2 range is less than 0.5%. © 2002 IEEE.|
