Dual-Band Waveform Generator With Ultra-Wide Low-Frequency Tuning-Range

Project Code :TVPGBE153

Objective

This paper presents a novel mixed-signal low-power dual-band square/triangular waveform generator (WFG) chip with a wide low-frequency tuning range for medical bio-electric stimulation therapy.

Abstract

This research paper introduces an innovative chip called the dual-band square/triangular waveform generator (WFG) designed for medical bio-electric stimulation therapy. The WFG chip operates at low power and combines analog and digital signals to generate square and triangular waveforms. It utilizes a relaxation oscillator consisting of a hysteresis Schmitt trigger and a timing integrator, as well as frequency divider (FD) stages and a path selector output for driving one electrode from a selection of 16 channels.

WFG chip operates on a supply voltage of ±1 V for the oscillator and +1 V for logic circuits. With on-chip passive components of small sizes (10 kΩ and 10 pF low oscillation frequency of 15 Hz. The WFG's core (band I) can be tuned within a range by adjusting the bias current, while a lower frequency range (band II) can be digitally set using a ÷2 stage.
