Abstract: This work presents a technique for the on- chip generation of analog sinusoidal signals with high spectral quality and reduced circuitry resources. The proposed generation technique consists of a modi ed low-order analog lter, that provides a sinusoidal out- put as response to a DC input, combined with a har- monic cancellation strategy to improve the linearity of the generated signal. The proposed generator has the attributes of digital programming and control, low area overhead, and low design e ort, which make this ap- proach very suitable as test stimulus generator for built- in test applications. An integrated prototype designed in a 180nm CMOS technology is presented in order to show the feasibility of the technique. Results obtained from the prototype show a THD around 80dB.
