摘要： Methods and systems for processing signals are disclosed herein. In one aspect of the invention a circuit for processing signals may comprise a triple well (TW) NMOS transistor coupled to an amplifier core. The TW NMOS transistor may track process and temperature variations (PVT) of at least one NMOS transistor within the amplifier core. A drain of the TW NMOS transistor may be coupled to a first inductor and the first inductor may be coupled to a first voltage source. The first voltage source may generate a standard voltage of about 1.2V. A source of the TW NMOS transistor may be coupled to a second inductor and the second inductor may be coupled to the first voltage source. A gate of the TW NMOS transistor may be coupled to a second voltage source, where the second voltage source may generate a standard voltage of about 2.5V.

摘要： A receiver and receiver front end having multiple independent differential inputs, multiple independent differential low-noise amplifiers, and two sets of double-balanced IQ mixers. The double-balanced mixers include cross-coupled PMOS devices that dynamically inject current at zero-crossing points to cancel out tail currents in the mixers. Also, methods of operating the above-discussed receiver and receiver front end.
