摘要: A low-noise amplifier includes a first transistor having a gate configured to receive an oscillating input signal and a source coupled to ground. A second transistor has a source coupled to a drain of the first transistor, a gate coupled to a bias voltage, and a drain coupled to an output node. At least one of the first and second transistors includes a floating deep n-well that is coupled to an isolation circuit.
