Implantable medical device having clock tree network with reduced power consumption

An implantable medical device having an integrated circuit for controlling a therapy delivery and a sensing function comprising:

• a clock source for generating a clock signal;
• a clock tree having a plurality of clock lines distributed within the integrated circuit for transmission of the clock signal;
• a plurality of clocked components, wherein each of the clocked components includes a data signal transmission path having a clocked component delay element and being connected to one of the plurality of clock lines;
• a first data signal line coupled between a data output of a transmitting clocked component of the plurality of clocked components and a data input of a receiving clocked component of the plurality of clocked components;
• and
• a clock tree delay element coupled to a clock line of the receiving clocked component to generate a modified clock signal, wherein the transmitting clocked component is configured to output the data subsequent to reception of the modified clock signal by the receiving clocked component.

A method of optimizing power consumption in an integrated circuit, comprising:

• transmitting a clock signal through a clock tree having a plurality of clock lines, wherein each of the clock lines is coupled to a plurality of clocked components;
• configuring a first of the plurality of clocked components as a transmitting clocked component coupled to a first of the plurality of clock lines;
• propagating a clock signal to the transmitting clocked component through the first clock line;
• measuring a duration of propagation of the clock signal to the transmitting clocked component;
• propagating the clock signal through a clock tree delay element coupled to a second of the plurality of clock lines to provide a modified clock signal to a first of the plurality of clocked components that is configured as a receiving clocked component;
• measuring a duration of transmission of the modified clock signal to the receiving clocked component;
• generating a data signal at the transmitting clocked component in response to receipt of the clock signal by the receiving clocked component;
• and
• transmitting the data signal from the transmitting clocked component to the receiving clocked component,
• wherein configuring the transmitting clocked component comprises providing a data transmission path within the transmitting clocked component having a clocked component delay element that yields a predetermined propagation duration of the data that results in receipt of the data signal by the receiving clocked component subsequent to receipt of the modified clock signal.
