Analog timer circuit with time constant multiplication effect

An analog timer circuit comprising:

• a pulse source;
• a charge storage element;
• and
• a charge pump coupled between the pulse source and the charge storage element;
• wherein a pulse signal generated by the pulse source is utilized to charge the charge storage element via the charge pump;
• wherein the analog timer circuit further comprises:
• a discharge pump coupled between the pulse source and the charge storage element;
• and
• a discharge distribution circuit coupled between the discharge pump and the charge storage element;
• wherein the discharge distribution circuit comprises first and second circuit paths separating energy from the discharge pump into respective first and second portions;
• the first circuit path providing the first portion of the discharge pump energy to the charge storage element;
• and
• the second circuit path diverting the second portion of the discharge pump energy away from the charge storage element;
• wherein the pulse signal generated by the pulse source is utilized to discharge the charge storage element via the discharge pump.
