This paper presents a dual-band power amplifier (PA) driver with matched output operating in the 2.4 GHz and 5.2 GHz ISM bands. The use of tunable differential inductors both in the RF choke and the matching circuit saves significant die-area compared to traditional configurations of integrated PA drivers. The fabricated circuit size is as small as 0.48 mm 2 for the used 0.18 μm CMOS process, saving about 0.5 mm 2 silicon area. Measurement results show that the circuit achieves 10.4 dB gain and a maximum output power of 13 dBm at 2.4 GHz while the gain is 5.1 dB and maximum output power is 8.7dBm at 5.2 GHz. The circuit dissipates 13mA from a 1.8V supply.Index Terms -Dual-band power amplifier driver, Power Amplifier (PA), dual-band, tunable inductor, preamplifier, PA driver.

“…In 2006, Broadcom designed a transceiver architecture based on low-pass filter multiplexing by using Gm-OTA-C integrator. The receiving filter and transmitting filter are both fourth-order Chebyshev's leapfrog architecture, with an adjustable range of 2-15 MHz or 10-25 MHz [14]. In 2009, Samsung designed a transceiver structure based on IF lowpass filter multiplexing by using a 5 th order Chebyshev Gm-C filter.…”

The design of 3 rd /5 th order active RC Chebyshev low-pass filter (LPF) with reconfigurable bandwidth and gain is based on 55 nm CMOS technology. The filter is integrated into draft IEEE 802.11ax concurrent dual band four antenna transceiver analog baseband circuit. Programmable capacitor bank of the filter is used to adjust bandwidth. The typical bandwidth of receiving filter is 10/20/40 MHz, and that of transmitting filter is 12/24/50 MHz. Adjust the gain ranging from -10 to 18 dB in passband by programmable resistor bank. The current consumption of typical bandwidth of receiving filter is 2.08 mA at a 1.5 V supply and has properties of 10 MHz bandwidth (BW), 36 dB gain, -62 dBm input signal, -39 dB third intermodulation distortion (IMD3), 17.1 nV/√Hz equivalent input noise (EIN). As for transmitting filter, the current consumption of typical bandwidth is 1.25 mA at a 1.5 V supply and has the properties of 10 MHz BW, -6 dB gain, 0 dBm input signal, -38 dB IMD3, 75 nV/√Hz EIN. Area of the whole filter is 0.08 mm 2 . INDEX TERMS Active RC, analog baseband, low-pass filter.

A low-IF receiver for WiMAX applications has been designed and fabricated in TSMC 1P8M 0.13-µm CMOS process. It contains an on-chip single-ended low noise amplifier, balun, double-balanced mixers, and an analog baseband which consists of programmable gain amplifiers and a fifth-order Butterworth channel selection filter. The programmable gain amplifiers provide 0 -65 dB gain range in 1dB step and less than 0.4 dB gain error. The bandwidth of the channel selection filter is reconfigurable from 2.5 MHz to 20 MHz for different requirements in WiMAX applications. The receiver has 4.6 dB noise figure and consumes 50.4 mW with a 1.2 V power supply. Index Terms-WiMAX, receivers, low IF, variablebandwidth filter, programmable gain amplifier (PGA).
