Hi:
I am studying BJT Amplifier configurations. Can someone tell me if I have the correct power formulae.

Common-Base / Common-Collector / Common-Emitter With Emitter Bias
DC Input Power:

PDC = ICQ * [VCC + |VEE|]

Maximum DC Power Dissipated By The Transistor:
PDQ = ICQ * VCEQ

Maximum AC Output And Input Power:
PAC = [0.707 * ICQ] * [0.707 * VCEQ ]
PIN = vIN2 / RIN


Common-Base / Common-Collector / Common-Emitter With A Bias
Method Other Than Emitter Bias

DC Input Power:

PDC = ICQ * VCC

Maximum DC Power Dissipated By The Transistor:
PDQ = ICQ * VCEQ

Maximum AC Output And Input Power:
PAC = [0.707 * ICQ] * [0.707 * VCEQ ]
PIN = vIN2 / RIN

Thanks
