The electronic device ( 100 ) of the invention comprises a semiconductor device ( 30 ) and a low-pass filter ( 20 ), which are present in a stacked configuration, and which together include a phase locked loop. The low-pass filter is preferably embodied by vertical trench capacitors, and preferably comprises a drift compensation part. The device ( 100 ) can be suitably provided in an open loop architecture. In a preferred embodiment, the low-pass filter comprises a large capacitor (C 2 ) and a small capacitor (C 1 ) connected in parallel, the large capacitor (C 2 ) being connected in series with a resistor (R 1 ).
