Biquadratic transconductance switched-capacitor filters [PDF]
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1993 The author presents a new type of sampled data filters consisting of transconductance, switches, and capacitors, called transconductor switched capacitor (TSC) filters. The implementation of this type of filter is particularly suitable for the CMOS integrated circuit technologies.

Testing mixed-signal cores: a practical oscillation-based test in an analog macrocell [PDF]
, 2002 A formal set of design decisions can aid in using oscillation-based test (OBT) for analog subsystems in SoCs. The goal is to offer designers testing options that do not have significant area overhead, performance degradation, or test time.
