10 CMOS Comparator Topologies — Design Details
Each topology below is available as a complete Cadence project with schematic, layout and IEEE 2026 base paper. Click any card details with our Cadence experts.
Type 01
Single-Stage Open-Loop Comparator
A single differential pair with active load driving output directly. Simple CMOS structure with moderate speed. Propagation delay ~2–5 ns at 180 nm. Suitable for slow, low-power applications where offset and hysteresis are not critical.
Type 02
Two-Stage Open-Loop Comparator
Differential input stage followed by a common-source gain stage for higher gain and better output swing. Miller capacitor can optionally stabilise the two-pole system. Wider output swing, improved DC gain, suitable for precision comparator applications.
Type 03
Folded-Cascode Comparator
Input differential pair with folded PMOS/NMOS cascode current mirror providing high output impedance and rail-to-rail input range. Excellent for low supply voltage designs (1.2 V–1.8 V). Very high DC gain with superior PSRR and CMRR.
Type 04
Hysteresis / Schmitt-Trigger Comparator
Positive feedback around a differential pair introduces programmable hysteresis window (VH − VL). Noise-immune digital interface and debouncing circuits. Hysteresis set by device W/L ratios. Simulated with Spectre transient showing clean noise immunity.
Type 05
StrongArm Latch Comparator
Clock-controlled regenerative latch topology with rail-to-rail output and near-zero static power. Widely used as the primary comparator in SAR ADCs, Flash ADCs and high-speed data converters. Propagation delay <200 ps at 45 nm. Low kickback noise with tail current source.
Type 06
Lewis-Gray Comparator
Classic double-differential-pair architecture proposed by Lewis and Gray, offering excellent input-referred offset cancellation. Widely referenced in IEEE JSSC literature for precision A/D conversion. Suitable for 8–10 bit ADC comparator designs in 90nm CMOS.
Type 07
Double-Tail Dynamic Comparator
Two separate tail current source structures split the pre-charge and evaluation phases, significantly reducing kickback noise to the input, which is critical in ADC applications. Energy per decision ~50 fJ at 45 nm. Ideal for IEEE 2026 high-speed ADC comparator projects.
Type 08
Preamplifier-Based Latched Comparator
A continuous-time preamplifier (gain ~10–20 dB) drives a StrongArm latch, effectively reducing input-referred offset and thermal noise of the latch. Common in high-resolution ADC front-ends. Offset simulated with Monte-Carlo mismatch analysis in Spectre ADE.
Type 09
Window Comparator
Two comparators with reference voltages VREF+ and VREF− whose outputs drive an AND/NAND gate to assert output only when VIN is within the valid window. Used in over/under-voltage protection ICs, battery management systems and ADC range detection circuits.
Type 10
Fully-Differential Comparator
Dual output topology (VOUT+ and VOUT−) with common-mode feedback (CMFB) circuit maintaining output common-mode voltage. Provides 6 dB better SNR than single-ended, superior even-order harmonic rejection and immunity to power-supply noise. Suitable for high-CMRR, low-noise ADC applications.

Which Cadence comparator topology is best for a SAR ADC project?
The StrongArm Latch Comparator is the industry-standard choice for SAR ADC designs due to its near-zero static power consumption, rail-to-rail output swing and propagation delay below 200 ps at 45 nm. For higher precision with better offset, the Preamplifier-Based Latched Comparator or Double-Tail Dynamic Comparator is preferred — the preamplifier reduces input-referred offset by its gain factor, and the double-tail structure minimises kickback noise. Both are available as complete IEEE 2026 Cadence Virtuoso projects from our Bangalore centre.
What simulation analyses are run for a Cadence comparator project?
Every Cadence comparator project includes the following Spectre analyses in ADE: (1) DC sweep — VTC (Voltage Transfer Characteristic) and switching threshold; (2) Transient — propagation delay (tpHL, tpLH), rise/fall time and output waveform; (3) AC analysis — gain-bandwidth and phase margin (for open-loop comparators); (4) Noise analysis — input-referred noise spectral density; (5) Monte-Carlo — mismatch-induced input-referred offset σ characterisation; (6) Corner analysis — SS/SF/FS/FF/TT PVT corners; and (7) Post-layout simulation — re-run transient/DC with PEX-extracted parasitics to confirm silicon-accurate performance.
What GPDK technology node should I choose for a comparator project?
GPDK 180 nm is best for beginner BE/BTech comparator projects — larger device geometries are easier to layout, SPICE models are well-characterised and DRC rules are more relaxed. GPDK 90 nm is recommended for MTech projects targeting moderate speed (sub-nanosecond) and lower power at 1.2 V supply. GPDK 45 nm is ideal for PhD-level projects targeting ultra-high-speed (StrongArm, Double-Tail) comparators at sub-1 V supply with <100 fJ energy per decision. All three nodes are available with full schematic, layout and Spectre model support at our Bangalore centre.
