Magnitude of equalization applied by a receiver equalization circuit varies across silicon process and environmental conditions. We propose a novel method to auto calibrate a programmable receiver equalization circuit to a target gain equalization value without the use of any external test equipment or channel. This method is built upon on-chip eye monitoring and internal loop back capabilities, which...
This paper describes a direct conversion transmitter for front-end Mobile WiMAX. The transmitter is implemented in 0.18μm CMOS technology and covers the frequency range 2.5-2.7 GHz. The components included in the system are Phase locked loop (PLL), phase frequency detector (PFD), Charge Pump (CP), TSPC based clock divider and Voltage Controlled Oscillator (VCO). On chip CMOS Class-AB Power Amplifier...
