dBm to Volts RF Engineers often express the power in dBm. The formula gives voltage value corresponding to a power value in dBm and Vice Versa. Following is the formula for dBm to RMS voltage conversion. P(dBm) = 10 log10(v2/(R*p0)) ...

1 dBm into a 50 ohm impedance translates to Vppof 0.71 Volt. The same power into half the impedance value gives a peak to peak voltage of 0.51 V. If a circuit requires 0 dBm power into it, then the equivalent voltage is 632 mVpp into 50 Ω. ...

所以到底是6dB还是3dB呢?或实际计算我应该用Power Sum还是Voltage Sum呢?在这个例子是比较特别的,因为两个讯号是coherent,所以计算上要考虑到讯号之间的的相位差,也就是Vtotal=V(1+cos(delta)),会有in-phase 与out-phase两个极端的结果,上面的例子很明显的为in-phase相加的结果,所以功率相加会多出6dB。
The class-D stage utilizes a cascode configuration, driven by an ac-coupled low-voltage driver, to allow a 5.5-V supply in the 1.2-/2.5-V technologies without excessive device voltage stress. The rms electric fields (E) across the gate oxides and the optimal bias point, where the voltage...
Let me use an analogy to try and explain. If you had a small light bulb, you could power it with 1W (=30dBm). It would light your room, but not very well. You could increase the overall illumination by raising the supply voltage, and increasing the power. ...
