Abstract:
A class AB amplifier includes a first inductor (L1) having a first terminal in communication with a voltage source terminal (Vdd). A first transistor (T1) has a drain terminal in communication with a second terminal of the first inductor (L1). A second transistor (T2) has a source terminal in communication with a source terminal of the first transistor (T2). A second inductor (L2) has a first terminal in communication with a drain terminal of the second transistor (T2) and a second terminal in communication with a reference potential (Vss). The drain terminals of the first transistor (T1) and the second transistor (T2) are capacitively coupled (Ccm) together.
