    Abstract: In an integrated free-fall detection device (16) for a portable apparatus (10), an acceleration sensor (20) generates acceleration signals (A x , A y , A z ) correlated to the components of the acceleration of the portable apparatus along three detection axes (x, y, z). A dedicated purely hardware circuit (24), connected to the acceleration sensor (20), generates in a continuous way and in real-time a free-fall detection signal (F). The free-fall detection signal (F) has a first logic value in the event that the acceleration signals (A x , A y , A z ) are simultaneously lower than a respective acceleration threshold (A th ), and is sent to a processor unit (18) of the portable apparatus (10) as an interrupt signal to activate appropriate actions of protection for the portable apparatus (10). The acceleration sensor (20) and the dedicated purely hardware circuit (24) are integrated in a single chip, and the acceleration sensor (20) is made as a MEMS.

    Abstract: A digital high-pass filter (12) has an input (IN), an output (OUT), and a subtractor stage (20), having a first input terminal, a second input terminal and an output terminal. The first input terminal of the subtractor stage (20) is connected to the input (IN) of the digital high-pass filter (12) and the output terminal is connected to the output (OUT) of the digital high-pass filter (12). A recursive circuit branch (21) is connected between the output (OUT) of the digital high-pass filter (12) and the second input terminal of the subtractor stage (20). Within the recursive circuit branch (21) are cascaded an accumulation stage (23), constituted by an integrator circuit, and a divider stage (24). The cutoff frequency (f t ) of the digital high-pass filter (12) is variable according to a dividing factor (den) of the divider stage (24).
