摘要： An input circuit for an integrated circuit (IC), which is mounted on a package having an input pin, rejects signal energy at a first frequency. A first bondwire arranged on the package has one end that communicates with the pin and an opposite end that communicates with components of the IC. A second bondwire located on the package has one end that communicates with the pin and an opposite end that communicates with a capacitance. The capacitance and an inductance of the first and second bondwires resonate at the first frequency to reject signal energy at the first frequency. Bondwires are also used to eliminate external components such as resonant components and impedance matching circuits to reduce cost.

摘要： A low noise amplifier includes an input stage. The input stage includes a first device configured to receive an input signal. A second device is connected to the first device. The second device has a predetermined input impedance. The input stage is configured so that a change in the input signal to the first device causes a linearly proportional change in a conductance of the first device. A voltage at a junction between the first device and the second device remains substantially constant due to the predetermined input impedance of the second device.
