Abstract
A digitally controlled variable capacitance integrated electronic circuit module () comprises a set of basic cells in a matrix arrangement. Each basic cell itself comprises a functional block () which can be switched between two individual capacitance values, a control block (), and a control junction connecting the control block and the functional block of said basic cell. The functional blocks and the control blocks are grouped into separate regions () of the matrix arrangement, to reduce capacitive interaction between output paths and power supply paths of the module. The functional blocks can still be switched in a winding path order within the matrix arrangement. A module of the invention can be used in an oscillator capable of producing a signal at 4 GHz.
