Brilliant mate! Appriciated

Hi, I think bottom left looks gnd and bottom right looks vcc. In output driver area pmos should be connected vcc and nmos should be connected gnd.

Can you please explain layout guide lines for ADC

Designing the layout for an analog-to-digital converter (ADC) involves several considerations: 1. **Separation of Analog and Digital Regions:** Keep analog and digital sections separate to minimize noise coupling. 2. **Grounding and Power Planes:** Ensure proper grounding and power distribution to minimize noise and voltage drops. 3. **Signal Routing:** Maintain short, direct traces for analog signals, and avoid crossing digital signals over analog traces. 4. **Clock Signals:** Route clock signals carefully to avoid skew and jitter, and use guard traces if necessary. 5. **Analog Shielding:** Use guard traces, ground planes, or shielding to protect sensitive analog signals from noise. 6. **Decoupling Capacitors:** Place decoupling capacitors close to the ADC to filter out noise and stabilize the power supply. 7. **Component Placement:** Position components based on signal flow and noise considerations, with sensitive components placed away from noisy sources. 8. **Analog Filtering:** Include appropriate RC filters or other analog filtering mechanisms to remove high-frequency noise. 9. **Parasitic Elements:** Account for parasitic capacitance and inductance in your layout design. 10. **Thermal Considerations:** Ensure proper heat dissipation for high-performance ADCs, and consider thermal vias and heat sinks. 11. **Grounding Techniques:** Employ star grounding, guard rings, and proper grounding practices to minimize ground loops. 12. **Cross-Talk Minimization:** Keep sensitive traces away from noisy traces to reduce cross-talk. 13. **Differential Pair Routing:** Maintain equal lengths and spacing for differential pairs to preserve signal integrity. 14. **Minimize Traces in Parallel:** Avoid running traces in parallel to minimize capacitive coupling. 15. **Layout Tools:** Utilize layout tools to ensure correct trace widths, spacing, and impedance control. 16. **Design for Testability:** Include test points and access for probing during testing and debugging. Remember, ADC layout is complex and can vary based on the specific ADC and application. Consult the ADC's datasheet and application notes for layout guidelines tailored to your device.
