ABSTRACT:
The invention relates to a low supply voltage analog multiplier which comprises a pair of differential cells, each cell comprising a pair of bipolar transistors with coupled emitters. A first transistor of each cell receives an input signal on its base terminal and has its collector terminal coupled to a first voltage reference through a bias member. Advantageously, the second transistor of each cell is a diode configuration, and the cells are interconnected at a common node corresponding to the base terminals of the second transistors in each pair. This multiplier can be supplied very low voltages and still exhibit a high rate of operation along with reduced harmonic distortion of the output signal, even with input signals of peak-to-peak amplitude above 600 mV.
