In this paper, the authors enable a receiver at a bias voltage at 0.6 V. This design employed a Low-Noise Amplifier (LNA) with a cascade structure and a mixer adopting the transformer isolation method for a separately biasing transistor. It has the equivalent effect of using a bias tee for the same separate biasing purpose, and occupies an area only the size of a transformer, which greatly decreases the area used on the chip. This design not only drives the mixer at 0.6 V, but also reduces the manufacturing cost of the chip.
