WiMAX (Worldwide Inter-operability for Microwave Access) is an emerging wireless technology standard, which enables high-speed packet data access. To anticipate future demands of WiMAX technology, we propose an all-digital phase-locked loop (ADPLL) based frequency synthesizer for the WiMAX RF transceiver. The developed ADPLL targets frequencies from(More)
—It is shown that an MOS weak-inversion differential pair can be linearized considerably by replacing the tail current source with a MOSFET biased in the weak-inversion triode region. Calculations show that the transconductance can be kept constant to within +5%/00% for input voltages up to 130 mV. This linearized differential pair is used in a third-order(More)
