In this paper, a low power three-stage CMOS amplifiers with 375x capacitive load (Ci) drivability will be presented. By employing the cascode Miller compensation, the non-dominant complex pole frequency is extended effectively and the physical size of the compensation capacitors is reduced. A local Q-factor control (LQC) loop is introduced to optimize the Q-factor when loading capacitance Cl changes...
This paper presents an ultra-low-power design technique for CMOS low noise amplifiers. Parallel capacitance with input transistor Cgs is discussed for reducing gate induced noise and make it an effective way to implement low power LNA with small transistor size and moderate biasing condition. This technique is more effective for advanced process with high transition frequency. A low power LNA is implemented...
A non-coherent 10Msps Ultra-Wideband (UWB) receiver using 3.1–5GHz pulse position modulation (PPM) signaling is implemented in a 65 nm CMOS process. The receiver is mainly comprised of low noise amplifier (LNA), squarer, integrator and comparator. All RF and baseband circuits operate at 0.5-V power supply. The chip area is 1.1mm×1.0mm. Total power dissipation is 7.44mW and 0.8nJ/bit can be achieved...
