This letter proposes a low noise amplifier which has low noise figure and high linearity simultaneously using a cascode structure with an additional transistor. The proposed structure minimizes the noise source by using optimizing transistor sizes and also improves linearity from the current bleeding technique. The device was fabricated in a
