... The overlap capacitances come from the Gate to Channel capacitors seen at the output. For M1, the device is always saturated so total Cgs = Cgs0 + Cgcs (saturation region): Cgs1 = (Co * W) + (2/3 * Cox * W * L) = (0.31f * 1) + (2/3 * 6f * 1 * 0.25) = 1.31 fF This does not get miller multiplied sinc ...

Power inverter
A power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC).The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.A power inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry.Static inverters do not use moving parts in the conversion process.
