Received Signal Strength Indication

A RF received signal strength indication (RSSI) circuit with 100MHz to 2.5GHz frequency bandwidth was designed based on Jazz 0.18 μm SiGe HBT process. The RSSI was composed of 4 cascaded limiting amplifier and full wave current rectifier. A novel DC offset compensation circuit was adopted to achieve stable operating point. The circuit was simulated with Cadence design kit. Results showed that the RSSI had a wide dynamic range from 45dBm to 0dBm, operated at a 3.3V single supply. The power consumption is 18.8mW.

Logarithmic Amplifier

This paper presents the design and realization of a low-noise, low-power, wide dynamic range CMOS logarithmic amplifier for biomedical applications. The proposed amplifier is based on the true piecewise linear function by using progressive-compression parallel-summation architecture. A DC offset cancellation feedback loop is used to prevent output saturation and deteriorated input sensitivity from inherent DC offset voltages. The proposed logarithmic amplifier was designed and fabricated in a standard 0.18[Formula: see text][Formula: see text]m CMOS technology. The prototype chip includes six limiting amplifier stages and an on-chip bias generator, occupying a die area of 0.027[Formula: see text]mm2. The overall circuit consumes 9.75[Formula: see text][Formula: see text]W from a single 1.5[Formula: see text]V power supply voltage. Measured results showed that the prototype logarithmic amplifier exhibited an 80[Formula: see text]dB input dynamic range (from 10[Formula: see text][Formula: see text]V to 100[Formula: see text]mV), a bandwidth of 4[Formula: see text]Hz–10[Formula: see text]kHz, and a total input-referred noise of 5.52[Formula: see text][Formula: see text]V.
