Jiguet Texas Instruments , Villeneuve Loubet, France In previous fully integrated transceiver publications [1,2], part of the receiver (RX), transmitter (TX), frequency synthesizer or power management were off chip. The transceiver we describe fully contains all these functions including VCO, loop filters, power amplifier (PA) controller, voltage regulators and voltage controlled crystal oscillator (VCXO) (Fig. 15.7.1). The chip area is 14mm2. The transmitter is a completely integrated translational loop st……
