Abstract :
A switched capacitor (SC) circuit is presented for realizing a one-dimensional discrete map generating 1/f noise. An integrated circuit with logarithmic and antilogarithmic amplifiers is included in this SC circuit to realize a nonlinear term xZ . An indirect time series analysis method using the Perron-Frobenius operator is applied to this map to precisely analyze its statistics such as the invariant measure, the autocorrelation function, and the power spectrum
