Abstract

This paper presents a 2.4GHz super-regeneration amplifier with capacitively-loaded integrated transmission line for a short range RF-pulse width transceiver. The degenerative quenching technique is employed in the super-regenerative amplifier to improve the linearity and reduces the sensitivity of negative transconductance (G_M) to the bias current. It 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 amplifier consumes 1.2mA and 1.5mA from 2.5V supply in transmit and receive mode for a data rate of 20Mb/s and a sensitivity of -95dBm.
