| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A 2.4GHz 0.13um CMOS Bluetooth transceiver achieving the high RX sensitivity and high-quality TX signals between -40C and +90C is presented. Low-IF receiver and direct-conversion transmitter architecture is employed. The receiver chain including an LNA utilizes a bias current synthesis scheme to compensate for temperature dependence of the gain, and achieves a sensitivity of -89.6dBm even in the worst environmental condition. Linearity optimization for the transmitter chain including a variable biasing circuit in a PA reduces the second harmonics of TX signals so that it suppresses the VCO pulling and keeps the carrier frequency drift within 18kHz. | |
