Abstract :
This paper presents an integrated transmission line super-regeneration amplifier (SRA) with degenerative quenching technique for short range impulse-FM-UWB transceiver. In transmitting mode, the SRA generates pulsed-sinusoids centered at two different tuned frequencies within 3.1GHz-3.8GHz to distinguish between data bit `1´ and `0´. In receiving mode, the SRA switches between filtering and oscillating modes with periodic change in the resonant frequency to detect the impulse-FM-UWB data pattern. The Q-enhanced degenerative quenching technique reduces the sensitivity of the negative transconductance (GM) over a wide range of bias currents. This also reduces the direct coupling of the high frequency quenching pattern to the resonator and the negative GM stage. The capacitively loaded integrated transmission line reduces the phase noise in transmit and receive modes. A test structure of the amplifier has been implemented in 0.25um BiCMOS technology. The SRA consumes 1.2mA and 1.8mA from a 2.5V supply in transmit and receive mode for a data rate of 10Mb/s and a sensitivity of -90dBm.
