Title:
INTEGRATED ELECTRONIC CIRCUIT COMPRISING AN OSCILLATOR WITH PASSIVE CIRCUIT ELEMENTS
Document Type and Number:
WIPO Patent Application WO1999021274
Kind Code:
A3
Abstract:
An electronic circuit with at least one active electronic component (10) and a delay element connected to the component. The delay element comprises an electric conductor (13, 18) which is composed of a conductive material on an insulating layer (14) such that the conductor's capacitive coupling to the surrounding becomes low. The conductor (13, 18) is drawn such that its inductance is minimized. The electronic component (10) and conductor (13, 18) are integrated in an integrated circuit. The delay element can be used in an oscillator coupling or in an electronically controlled antenna. In the oscillator coupling the electronic component (10) comprises an inverter coupling (11) with an input (11) and an output (12). The conductor (13) is provided to connect input (11) with output (12), thus creating an oscillator. The electronically controlled antenna comprises a receiver (17) and a number of antenna elements (16) connected to the receiver (17). Individual antenna elements (16) are connected to the receiver (17) via automatically selectable delay elements (18) such that electric signals from different antenna elements (16) are differentially delayed dependent on the position of the antenna elements in relation to the impinging electromagnetic wave fronts.
