The proposed circuit is simple and usable up to 100\u00a0MHz with the advantage of electronically controlled threshold levels and amplitude of the output. The circuit is also little sensitive to temperature and benefits from low power dissipation (0.5\u00a0mW). The amplitude of the output current is tunable electronically from 5\u00a0nA to 500\u00a0\u03bcA, which is a wide tunable range. The effects of transistors mismatch on proposed Schmitt trigger have also been explored. The utility of the proposed circuit is further justified through its application as a triangular\/square wave generator, with a maximum frequency of 75\u00a0MHz. Duty cycle modulation through electronic means is also shown for the generator circuit, where duty cycle results for 80, 20, and 95% have been included, by varying external control current. The cadence<jats:sc>VIRTUOSO<\/jats:sc>simulation results by using generic process design kit 90\u2010nm technology are shown to confirm the proposed theory. The proposed circuits are also verified through experimental results by using commercial integrated circuits: AD844 and LM13700. All the simulated and experimental results promise potential applications of the proposed circuits in instrumentation and communication systems.
