Abstract :
The analysis, design and implementation of a S2I switched-current multiplier is presented. A thorough circuit analysis of the multiplier and its nonidealities is presented with a design procedure. It has been implemented using a 2 μm n-well CMOS technology. The following are brief highlights of the measurement results: (i) 0.425 millions of multiplication per second, (ii) 1.7% total harmonic distortion for a sinusoidal of 35 μA (50 Hz), (iii) 206 kHz of bandwidth, (iv) 50 dB of SNR and (v) 0.3 mW zero input power consumption for a ±3 V power supply. A complete set of detailed experimental results is provided in the paper
