Description	The designed triangular ramp generator with single ended output can be used in pulse width modulation (PWM) aplication (for example for DC / DC converters, D class inverters or amplifiers). The output signal of the proposed generator has a double edge and advantage of this shape improve transient characteristics of the system. Another advantage is that by creating the desired output waveforms, the discharge current peaks, created by the generator with the output signal form of the saw, disappear. Originality of the design of the sawtooth signal generator consists mainly in the use of new control loops, ensuring a low power consumption in a wide range of operating frequencies. This is due to the fact that comparators are not used in the proposed generator for detecting threshold levels of the output signal. The actual generator requires no external components and also does not need trimming. High linearity of the output signal as well as the autonomy of the generator is ensured by the control loops that control the amplitude, the charging rate and the mean value of the output signal. The device is fully integrated and is manufactured in CMOS technology HCMOS9GP 130 nm. The fabricated die is packaged in QFN 40 package.
