A Novel Programmable CMOS Based Function Generator Circuit
نویسنده
چکیده
In this paper, design and analysis of a programmable CMOS-based function generator circuit is presented. The proposed circuit implements trapezoidal and triangular functions with all parameters (slope, position, width and height) independently and continuously adjustable. The proposed circuit achieves higher speed compared to the available previous work by not using winner takes all or looser takes all circuits which are common in design of function generator circuits. The circuit is designed and simulated in 0.13 um CMOS technology, and is suitable to be used in analog and mixed-mode integrated circuits.
