This paper presents a low-power on-chip RC oscillator with compensation for temperature and supply voltage variation. This circuit is based on a conventional on-chip oscillator, with only a capacitor and a comparator to avoid mismatch. Multiple current sources flow through the same resistor to generate a reference voltage. This is complemented with the dynamic element matching technique to reduce...
This paper presents a high linearity time-mode temperature sensor with close-loop architecture. The main loop utilizes a switched-capacitor equivalent resistor (Reqsc) to convert the linear values of ΔVBE and the output period of a Voltage-Controlled-Oscillator (VCO) into the control voltage of the VCO. A temperature independent equivalent resistor (Req) whose value only depends on clock period and...
This paper presents a high speed and low distortion sampler with two-channel time-interleaved sampler with track-and-hold amplifier (THA). The THA is based on switched source-follower with active inductor load such that wide bandwidth in tack-mode and small signal feed-through in hold-mode can be both achieved within compact area. Furthermore, one clock-controlled auxiliary transistor is also introduced...
