摘要： An amplifier (e.g., an LNA) with improved ESD protection circuitry is described. In one exemplary design, the amplifier includes a transistor (410), an inductor (412), and a clamp circuit (422). The transistor (410) has a gate coupled to a pad (450) and provides signal amplification for the amplifier. The inductor (412) is coupled to a source of the transistor (410) and provides source degeneration for the transistor (410). The clamp circuit (422) is coupled between the gate and source of the transistor (410) and provides ESD protection for the transistor (410). The clamp circuit (422) may include al least one diode coupled between the gale and source of the transistor (410). The clamp circuit (422) conducts current through the inductor (412) to generate a voltage drop across the inductor (412) when a large voltage pulse is applied to the pad (450). The gate-to-source voltage (Vgs) of the transistor (410) is reduced by the voltage drop across the inductor (412), which may improve the reliability of the transistor (410).

摘要： A high-frequency amplifier includes a bipolar transistor with its emitter grounded. A DC bias to the base of the bipolar transistor is applied from either a constant-current source or a constant-voltage source depending on the power level of the high-frequency signal to or from the bipolar transistor. A frequency mixer uses a configuration for applying a DC bias to the base of the bipolar transistor in the high-frequency amplifier in order to apply a DC bias to the base of a bipolar transistor for high-frequency signal input and/or the base of a bipolar transistor for local oscillator input.
