Disclosed is a pixel element comprising a semiconductor substrate, a primary charge-collection node, a peripheral node, a modulating node, a circuitry and a backside conductive layer. The semiconductor substrate is configured to convert a flux of photons to first and second conductivity-type mobile charges. The peripheral node at least partially surrounds the primary charge-collection node, which at least partially surrounds the modulating node. The circuitry is used to connect and disconnect a reset voltage to/from the primary charge-collection node, provide a peripheral node voltage to the peripheral node, and measure an amount of the first conductivity-type mobile charges collected by the primary charge-collection node. The modulating node is electrically connected to a modulating voltage source, which is independent of the peripheral node voltage. The backside conductive layer is configured to collect and conduct the second conductivity-type mobile charges, and configured to be electrically connected to a bias voltage.

A sequential circuit with timing event detection is disclosed. The sequential circuit has an input that is asserted to the output during the second clock phase of a two phase clock signal. A timing event detector is coupled to the sequential element input to assert a timing event signal if a transition occurs at the sequential element input during the second clock phase but not to assert during the first clock phase.

According to the invention, only one type of enhancement MOS transistor type is used in implementing typical Boolean functions in hardware. Preferably, the MOS transistor type allows back bias control for adjusting and compensating the operation conditions. When implemented in PMOS only transistors, the pull-down functionality is performed by a single transistor with its gate and source connected to the output. This type of connection ensures that the pull-down functionality is performed by the leakage current of the pull-down transistor. The leakage currents of all the pull-up transistors need to be smaller than this pull-down current when all the pull-up paths are off. The ratio of these off-currents can be adjusted by the aspect ratios of the transistors. The logic type offers extremely low current consumption with low voltages and offers the possibility to avoid more complex shut-down circuitry often used in ultra low-power designs. The logic type offers higher operation speed compared to the existing solutions.

A level shifter comprises a first control switch () for connecting an output terminal to a first supply voltage (VDDH) to set an output signal to be high, and a second control switch () for connecting the output terminal to a signal ground (GND) to set the output signal to be low. The level shifter comprises a pre-charging switch () for connecting the output terminal to the first supply voltage, and an input gate circuit () for controlling an ability of an input signal to control the second control switch. The level shifter comprises a keeper circuit () for controlling the first control switch based on the output signal. The first control switch is controlled with the first supply voltage when the output signal is low, and with a second supply voltage that is between the first supply voltage and the signal ground when the output signal is high.
