M. Steyaert et al., A HIGH-PERFORMANCE RDS-DETECTOR FOR LOW-VOLTAGE APPLICATIONS, Analog integrated circuits and signal processing, 8(1), 1995, pp. 7-19
The design and realisation of the analog part for an RDS-receiver, the
RDS-detector, is discussed in this paper. The RDS-receiver is develop
ed towards low voltage applications (1.8 V) with low power consumption
requirements. A new topology for RDS-receivers is introduced resultin
g in an important quality improvement, mainly being a higher phase-lin
earity and a lower power consumption. The performance of the chip is c
ompared to existing RDS-receivers. These receivers use an analog integ
rated bandpass filter. In the presented topology direct conversion fol
lowed by lowpass filtering is used. The chip is realised in a fully di
fferential switched-capacitor technique with correlated double samplin
g. The latter is used to obtain a very low equivalent input DC-offset.
The chip is implemented in a 2 mu m BiCMOS technology.
