Abstract :
This paper presents the most important properties of log-domain filters for the realization of low-voltage and low power analog signal processing circuits. The noise behavior is discussed and the advantage of the combination of companding and class AB operation is highlighted. Examples of BiCMOS and CMOS realizations operating at supply voltages as low as 1 V are presented
