Quizplus · Accepted Answer

In a Schmitt-trigger configuration using an OTA (Operational Transconductance Amplifier), the trigger points are controlled by both the output current (IOUT) and the bias current (IBIAS). The IOUT influences the switching thresholds by altering the effective transconductance of the OTA, while IBIAS directly affects the internal biasing conditions, thereby adjusting the trigger levels.
