dc.descriptionIn this work we present the design of a digitally controlled ring type oscillator in 0.5 μm CMOS technology for a low-cost and portable radio-frequency diathermy (RFD) device. The oscillator circuit is composed by a low frequency ring oscillator (LFRO), a voltage controlled ring oscillator (VCRO), and a logic control. The digital circuit generates an input signal for the LFO, which generates a voltage ramp that controls the oscillating output signal of the VCRO in the range of 100 KHz to 1 MHz. Simulation results show that the proposed circuit exhibits controllable output characteristics in the range of 100 KHz – 1 MHz, with low power consumption and low phase noise, making it suitable for a portable RFD device.
