چکیده
Equations describing the high-frequency nonlinear behavior of common-emitter and differential-pair transconductance stages are derived. The equations show that transconductance stages using inductive degeneration are more linear than those using capacitive or resistive degeneration, and that the common-emitter transconductance stages are more linear than the differential-pair transconductance stages with the same bias current and transconductance. The nonlinearity equations can also be used to explain the class AB behavior of the commonemitter transconductance stage with inductive degeneration.

A Low Power Low Voltage Rail to Rail Constant gm Differential Amplifier with 150 dB CMRR and Enhanced Frequency Performance
This paper proposes a low voltage (±0.55V supply voltage) low power (44.65µW) high common mode rejection ratio (CMRR) differential amplifier (d.a.) with rail to rail input common mode range (ICMR), constant transconductance (gm) and enhanced frequency performance. Its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...

-In this paper, a necessary and sufficient condition for robust stability of electronic circuits at high frequency which contain differential pair (emitter-coupled pair) is proposed. In fact, when emitter-coupled pairs are used as one input signal – one output signal, they have uncertainty in their transfer functions at high frequency. Even as will be shown, this uncertainty can be caused insta...

متن کاملA Nyquist-Rate Pixel-Level ADC for CMOS Image Sensors - Solid-State Circuits, IEEE Journal of
A multichannel bit-serial (MCBS) analog-to-digital converter (ADC) is presented. The ADC is ideally suited to pixel-level implementation in a CMOS image sensor. The ADC uses successive comparisons to output one bit at a time simultaneously from all pixels. It is implemented using a 1-bit comparator/latch pair per pixel or per group of neighboring pixels, and a digital-to-analog-converter/contro...
