We introduce a class of deterministic push-down transducers called concatenation state machine (CSM) and we study its semantic domain which is a class of parial mappings over finitely generated free monoids, called simple functions.
Millimeter-Wave (MMW) frequencies offer large bandwidths for communication, radar and imaging. Moreover, antennas can be realized in small dimensions, resulting in miniaturized transceiver systems. In such systems, the cost is a big obstacle limiting their mass application. Analog MMW-transceiver chipsets have been demonstrated in [1-3], where the cost is… (More)
The measurement results as well as the theoretical background are presented. The chips were fabricated in a 0.35 µm BiCMOS-technology and operate at a supply voltage of 2.7 V.
