A photomask for negative-tone development (NTD) includes a main region, and a scribe lane region surrounding the main region and including a first lane and a second lane. The first and the second lane is provided at first opposite sides of each other with respect to the main region. The first lane includes a first sub-lane extending in a first direction and a second sub-lane that extending in the first direction. The first sub-lane includes a first dummy pattern and the second sub-lane includes a second dummy pattern. The first dummy pattern and the second dummy pattern are configured to radiate light exceeding a threshold dose of light to a first portion of a negative-tone photoresist provided under the first lane of the photomask.

A switched capacitor circuit includes a first main sampler circuit, a second main sampler circuit, a first replica sampler circuit, and a second replica sampler circuit. The first main sampler circuit samples a first input of a differential input, and generates a first output corresponding to the sampled first input based on a first reference voltage. The second main sampler circuit samples a second input of the differential input, and generates a second output corresponding to the sampled second input based on a second reference voltage. The first replica sampler circuit receives the first input, and holds the received first input based on the second reference voltage. The second replica sampler circuit receives the second input, and holds the received second input based on the first reference voltage.

An analog to digital converter includes a digital to analog converting circuit, a comparator and a signal processing circuit. The digital to analog converting circuit samples and holds an analog input signal, and converts digital output data to an analog signal to generate a hold voltage signal. The comparator compares the hold voltage signal with a reference voltage signal in response to a rising edge and a falling edge of a clock signal to generate a comparison output voltage signal. The signal processing circuit performs successive approximation based on the comparison output voltage signal to generate the digital output data.

A power control method for tracking a Maximum Power Point (MPP) in a photovoltaic system including a solar cell and a boost converter. The power control method includes finding the MPP by applying a continuous ON/OFF signal to the boost converter as a first control signal for controlling a duty ratio of the boost converter, and maintaining an operating point of the photovoltaic system at the MPP by applying a second control signal for controlling the duty ratio to the boost converter depending on a constant-voltage command. In tracking an MPP in a photovoltaic system, an MPPT algorithm may remain at the MPP, without self oscillation, improving fast dynamic characteristics upon a change in solar radiation.
