A low-power, high-gain CMOS low noise amplifier (LNA) for use as the first stage of a subsampling receiver is proposed. The performance of +96 dB voltage gain and less than 1 dB noise figure (NF) with very low power consumption is reported for the first time and makes it suitable for use in a subsampling mixer with track and hold (T/H) circuit. The LNA contains both tuned and inductorless amplifier stages. The first stage utilizes optimum transistor gate width-length ratio (W/L), improved-Q on-chip spiral inductors, fully differential architecture, and current-reuse techniques to achieve low-noise, high-gain, and low-power at the same time. The following stages are inductorless amplifiers designed to achieve the maximum-gain. Cascode transistors are used in all stages to maintain reasonable gain at high frequencies and to achieve good reverse isolation. The amplifier linearity is sacrificed as a consequence of its high gain. |
