  • Low noise amplifier with low noise, high isolation bias circuit
    Publication number: 20060091959
    Abstract: A low noise amplifier and method for amplifying an input signal uses a high impedance electrical element having both inductance and capacitance connected between an output transistor and a bias circuit to provide noise isolation between the bias circuit and the output transistor. The noise isolation provided by the high impedance electrical element reduces the amount of bias circuit noise introduced into the output signal. In an embodiment, the high impedance electrical element includes an inductor and a capacitor connected in parallel. In another embodiment, the high impedance electrical element includes a grounded transmission line.
