    • A system for treating a hydrocarbon containing formation includes a steam and electricity cogeneration facility. At least one injection well is located in a first portion of the formation. The injection well provides steam from the steam and electricity cogeneration facility to the first portion of the formation. At least one production well is located in the first portion of the formation. The production well in the first portion produces first hydrocarbons. At least one electrical heater is located in a second portion of the formation. At least one of the electrical heaters is powered by electricity from the steam and electricity cogeneration facility. At least one production well is located in the second portion of the formation. The production well in the second portion produces second hydrocarbons. The steam and electricity cogeneration facility uses the first hydrocarbons and/or the second hydrocarbons to generate electricity.

    • Two compensating resistors in a mirror bias circuit coupled to a radio frequency (RF) amplifier are configured such that transistor base-emitter voltages are adjusted to stabilize RF transistor quiescent current for variations in collector voltage, Vcc. For example, when battery power is drained during device use, Vcc decreases. As Vcc decreases, less current is drawn through the compensating resistors, thereby decreasing the voltage drop across the compensating resistors and increasing the transistor base-emitter voltages in the mirror bias circuit and the radio frequency (RF) amplifier. Thus, the tendency of the RF transistor quiescent current to decrease as Vcc decreases is off-set because the compensating resistors cause an increase in the RF transistor base-emitter voltage, thereby increasing quiescent current. In one embodiment, the first compensating resistor size is equal to the second compensating resistor size multiplied by the ratio of the buffer transistor current rating to the mirror transistor current rating.
    • 耦合到射频(RF)放大器的镜偏置电路中的两个补偿电阻器被配置为使得晶体管基极 - 发射极电压被调整以稳定RF晶体管静态电流以用于集电极电压Vcc的变化。 例如,在设备使用期间电池电量耗尽时,Vcc减小。 随着Vcc的减小,补偿电阻器的电流越小,从而降低补偿电阻器两端的电压降,并增加镜面偏置电路和射频(RF)放大器中的晶体管基极 - 发射极电压。 因此,由于补偿电阻引起RF晶体管基极 - 发射极电压的增加,RF晶体管静态电流随着Vcc的降低而降低的趋势是偏移的,因此增加了静态电流。 在一个实施例中,第一补偿电阻器尺寸等于第二补偿电阻器尺寸乘以缓冲晶体管额定电流与镜面晶体管额定电流的比率。
