In this paper, we designed a 1.2-V low supply voltage transconductance-C (Gm-C) low pass filter (LPF) for transmitter analog baseband front-end of wireless local area network (WLAN) transceiver applications. The filter's cut-off frequency is 10MHz and PIIP3 is 8.4dBm. The LPF uses a 3rd-order Chebyshev prototype. The filter is fabricated in TSMC 0.13-μm CMOS technology and drains 3.8mA from a 1.2-V...
In this paper, an integrated DC-DC (Buck) converter is presented. The Buck converter has two modes of operation. The continuous mode is used for heavy loads, and the pulse-skipping modulation (PSM) mode is used for light loads. To optimize the Buck converter efficiency in PSM mode, an ON-time control loop is utilized. Short-circuit and over-temperature protection schemes are used to improve the design...
