+## Problem 1
+You are synthesizing a chip composed of random logic with an average activity factor of $\alpha = 0.1$. You are using a standard cell process with an average switching capacitance of $C_\text{avg} = 450$[pF/mm$^2$]. Estimate the dynamic power consumption of your chip if it has an area of 70[mm$^2$] and runs at 450[MHz] at $V_{DD} = 0.9$[V].
+
+$P_\text{dynamic} = C_\text{sw} V_{DD}^2 f_\text{sw}$
+
+```python
+alpha = 0.1                     # Activity factor
+C_avg = 450E-12                 # Average switching capacitance [F / mm^2]
+A = 70                          # Chip area [mm^2]
+f = 450E+6                      # Clock frequency [Hz]
+V_DD = 0.9                      # Supply voltage [V]
+
+C_sw = C_avg * A                # Total switching capacitance [F]
+f_sw = alpha * f                # Switching frequency [Hz]
+
+P_sw = C_sw * V_DD**2 * f_sw    # Dynamic power [W]
+
+print(f"Dynamic Power: {P_sw}")
+```
+
+$\boxed{P_\text{dynamic} = 1.148175\text{[W]}}$
