- 論文の詳細を見る
Piecewise linear (PWL) circuit modules operating on sigma-delta (ΣΔ) modulated signals and nonlinear signal processors built of these modules are proposed. The proposed module library includes absolute circuits, min/max selectors and negative resistances. Their output signal-to-noise ratio is higher than 50dB when their oversampling ratio is 2^8. A nonlinear filter and a stochastic resonator are presented as applications of the PWL modules to ΣΔ domain signal processing. The filter is structured with 37% of logic gates consumed by an equivalent filter with a 5-bit parallel signal form.
