### POR (Power On Reset) Circuit
Power-on reset (POR) circuit ensures that electronic systems start up in a known, stable state by generating a reset signal when power is initially applied. This circuit detects when the power supply reaches a sufficient voltage level and holds the reset line active until the voltage stabilizes, preventing erratic behavior and data corruption. POR circuits are crucial in microcontrollers, consumer electronics, and industrial systems, as they guarantee reliable initialization and consistent performance, thereby enhancing system stability and functionality during power-up.The circuit designed without capacitor which yields 30% reduction of chip’s area compared to the conventional designs

3. **Frequency Response**: Analyze the frequency response of the op-amp by sweeping through various frequencies and recording the output using the Analog Discovery's built-in tools.
4. **Transient Analysis**: Measure how the op-amp and power-on-reset circuits respond to transient signals or sudden changes, such as power-up events.
5. **Voltage Levels**: Check the stability and correct operation of the power-on-reset circuit by measuring the voltage levels and timing of the reset pulse.
