class="label">•: A new light to time converter (LTC) is proposed to detect wide luminance ranges.
class="label">•: The proposed LTC is a simple, compact, and low-power circuit with no bias current.
class="label">•: The converter has a fast response and is suitable for high-speed imaging.
class="label">•: Its performance is robust against supply voltage and process parameter variations.
class="label">•: By using the proposed LTC, a high performance PWM based DPS is designed.
