Abstract
Described herein are reduced-power electronic circuits with wide-band energy recovery using non-interfering topologies. A digital logic driver comprising a pulldown switch, an energy saving component (e.g., inductor) coupled in series with the pulldown switch, and a reference supply connected in series with the energy saving component that is configured to enable the digital logic driver to resonate with a load capacitance and reuse electrical energy at the load capacitance without interfering with a signal path of the digital logic driver.
Claims19
A digital driver having a wide operating frequency range, comprising:
- a pulldown switch;
- a pullup switch;
- an energy saving component coupled in series with the pulldown switch and the pullup switch;
- and
- a reference supply connected in series with the energy saving component that is configured to enable the digital driver to resonate with a load capacitance and reuse electrical energy at the load capacitance without interfering with a signal path of the digital driver having the wide operating frequency range due to the energy saving component being electrically coupled to the signal path periodically, wherein the pullup switch is designed with a first ratio of width to length that is less than a second ratio of width to length of the pulldown switch due to functionality of the pullup switch being partially performed with energy recycling resonance when the driver resonates with the load capacitance.
A method of operation of a digital driver, the method comprising:
- series connecting a first terminal of an inductive component to a pulldown switch and a pullup switch of an inverter with an automated digital auto place route design tool;
- series connecting a second terminal of the inductive component to a lower voltage bias of the inverter;
- and
- configuring the inductive component to enable the digital driver to operate in a resonant mode and reuse electrical energy at a load capacitance without interfering with a signal path of the digital driver due to the energy saving component being electrically coupled to the signal path periodically, wherein the pullup switch is designed with a first ratio of width to length that is less than a second ratio of width to length of the pulldown switch due to functionality of the pullup switch being partially performed with energy recycling resonance when the driver resonates with the load capacitance.

- and
- a bias voltage connected in series with the pulldown switch and the first inductive component that is configured to enable the digital driver to have generalized series resonance with a load capacitance and reuse electrical energy at the load capacitance without interfering with a signal path of the digital driver having the wide operating frequency range due to the energy saving component being electrically coupled to the signal path periodically, wherein the pullup switch is designed with a first ratio of width to length that is less than a second ratio of width to length of the pulldown switch due to functionality of the pullup switch being partially performed with energy recycling resonance when the driver resonates with the load capacitance.
