Abstract :
The application of switched-current techniques for nonlinear sampled-data signal processing is a new application area compared with the switched-current frequency domain linear filtering applications. This paper proposes several new switched-current circuits for nonlinear signal processing. These are switched-current pulse-width modulator, switched-current current-controlled oscillator and switched-current multiplier-divider. The proposed circuits present merits of simple circuit configuration, low voltage and low fabrication cost
