Abstract

A low power high linear transmitter for mobile WiBro and WiMAX is developed. The transmitter is fabricated in a 0.18 μm 1P6M CMOS process for low power characteristics and SoC compatibility. To achieve high linearity performance with low power consumption, the transmitter employs new linearization methods. Linear transconductor is used for the transmitter mixer. The transconductor utilizes a negative feedback amplifier and a current mirror amplifier (CMA). In addition, a multiplegated transistor (MGTR) with two auxiliary transistors and resistive source degeneration are used for the driver amplifier. With the proposed linearization techniques, a high linearity of 30.5 dBm OIP3 is achieved with 97.2 mW power consumption from a 1.8 V supply.
