Trans-impedance Amplifier for Gas Sensor Analog Front-end
Transimpedance Ampllifier(TIA) amplifies current to voltage. Nested chopper technique, Weak Inversion design aloow low noise, low offset structure. In low frequency, the signal can be amplified in different ranges. TIA circuit is implemented in tsmcTM 0.18nm BCMMOS technology. Chip size is 1.175mm x 1.175mm.
Single to Differential Programmable Gain Amplifier (SD-PGA)
This SD-PGA converts a single-signal into an amplified differential-signal that is adjusted by user-programmble register. It is designed in 130nm BCDMOS technology, which consists of a high gain amplifier and gain controller.
Bandgap Reference with Temperature Sensor
This Bandgap Reference (BGR) is able to generate precise output voltage that is independent of process, supply load and temperature variation. Temperature sensor detects certain voltage at temperature which increases linearly with temperature.
SUN FSK RF Low Power Transceiver
This IP is a RF low power transceiver for smart utility system network with using the frequency shift keying method. This IP operate at a multi data-rate, multi-rate (50 kbps/150 kbps/200 kbps) frequency shift keying (FSK) modulation is implemented using a phase-locked loop (PLL) with a programmable loop bandwidth.
12bit Biopotential Analog Front-End for ECG and EEG
This IP is biopotential AFE (Analog Front-End) for measuring EEG and ECG. The AFE is based on the AC-coupled chopper stabilization, and achieves high input impedance and high CMRR.
